Two days later:

Katara's POV:

I plop the last patient's notes in the cupboard and push back my chair with a sense of relief as I stretch my arms over my head. A moment later, I feel a something light tap me on the crown of my head and when I glance up I find Yun looking down at me with a fond smile and a folder resting on my head.

"Done for the day?" He asks as he removes the folder. I grin and nod.

"Yep, feels good to go home." I joke as I stand up.

"That it does, today's shift was a hectic one." He says as he pulls a face. "I noticed your car wasn't parked, do you need a lift?" My colleague offers. I smile sheepishly

"Yeah, it's at the garage today; I kept meaning to ask if you didn't mind giving me a lift home after work." I admit as I rub the back of neck in embarrassment. He laughs and waves a hand for me to follow.

"Of course. I've given you lifts before, nothing new." Yun replies with a wink. I roll my eyes and move to follow him.

As we move through the department, my eyes accidentally meet Kiki's. The nurse was someone I was very close to, until I found out my ex-husband was asking her to keep tabs on me without my permission. Our easy friendship had soured after that. It has improved, but it's still very awkward.

As soon as our eyes meet, Kiki immediately drops her gaze to the floor and turns around, busying herself with a fluid stand. I sigh and shake my head to myself. 'There are some things that never improve with time.' I think mournfully as we head for the exit. It's raining outside and I impulsively bend a water umbrella over the two of us. Yun whips out his car keys and starts swinging them around his finger.

"You're going to drop them if you do that." I tease eliciting a snort from the man.

"An emergency consultant like myself would never do that." He responds broadly, only for the keys to slip off his finger. I bend a stream of water from the rain to catch the key before they drop in a puddle and bend them back into the older man's hand. Yun shoots me a sheepish look as he opens the car door and I can't help but laugh.

"Sure, you won't." I joke as I open the car door and slide into the passenger seat. The doctor follows suit and closes his door as he starts the engine.

"Ok maybe I was a bit too confident there." He says with a chuckle and starts pulling out of the hospital car park. I smile and rest my elbow against the window sill as I watch the rain patter against the windscreen.

"I gave it some thought." I say after several moments of silence. Yun blinks and gives me a side glance before focussing on the road.

"I see." Is all he says. I take in a deep breath.

"If we...got engaged and we moved in for a trail period, would that be alright?" I ask haltingly, anxious that he'll shoot the idea down immediately. I watch as he purses his lips and taps his fingers against the driving wheel.

"It's fine by me, but you're the one who looks anxious." Yun jokes as he slows to a stop at a red light. I flush and turn my head.

"Sorry, I just..." I start, but the man shakes his head.

"You don't need to apologise. This is a big change for you, I get it." The doctor reassures with a smile which eases the tension from my body.

"Thanks." I utter gratefully, he shoots me another smile before refocussing back on the road.

"What about Yatsu? Have you talked to him?" Yun asks as he makes a right turn. I give a half smile.

"I did. It's part of why I'm suggesting an adjustment period to see how the four of us feel without fully committing, if that makes sense?" I try to explain, but I feel my tongue twist and I stumble mid-way. "He loves you and Fuki, but I think..." I pause, not wanting to say that he's thinking about his own biological dad, but Yun seems to pick up on it straight away.

"No, you're right. For all his life, it's just been him and you. Having a Dad and a sibling would be a big change for him, he needs to adjust and see if he likes it first. It's very sweet of you to put Yatsu's needs first. I made that mistake with Fuki and it's why I've been careful who I let into my life because of it." Yun confesses with a look of shame, but I shake my head and reach out to touch his elbow lightly.

"You're only human. We naturally crave companionship, it's not wrong to go after it." I reassure kindly and only until he gives me a smile do I retract my hand.

"I appreciate that, Katara." Yun voices gratefully. I nod my head in encouragement as I finger the locket around my neck absent mindedly.

"Of course. So, would that be ok? If we stayed at yours for a bit and see how it goes?" I ask after an age, eliciting a smirk from the man.

"You think I'd say no to having a beautiful lady like yourself and a dashing young boy like your son living at mine?" The doctor teases with a wink. I flush red and elbow him lightly in the side.

"Don't say stuff like that!" I rebuke as my heart flutters slightly. The man's laugh vibrates the whole car.

"I love seeing you flustered like this; it's such a rare sight." Yun says with a chuckle as he gives me a sidelong glance. I roll my eyes.

"Shouldn't you be keeping your eyes on the road?" I retort dryly and he snaps his gaze ahead of him once more.

"Killjoy." He mumbles, eliciting a snort from me.

"Rightfully so." I counter and this time he snorts as he turns on the indicator.

"Anyway, I'm more than happy to move things along. Just let me know the move-in date." Yun asks smoothly as we park outside my house. I bite my lip at his question.

"Well, it's Friday today, so I was thinking over the weekends?" I suggest shyly just as the man switches off the ignition. His hand freezes on the car keys as he turns around to face me with surprise.

"Are you sure? That's so soon." My friend asks with underlying concern, but I nod my head firmly.

"I don't want my nerves to get the best of me, so the sooner the better." I confirm as the man wears a dubious expression.

"Maybe that's more of a reason for you to think this over?" He advises, but I'm already shaking my head before he has finished his sentence and I reach out to hold his free hand.

"Please Yun. I want to give us a shot and I don't want to wait. We've known each other for so many years already and friends for nearly as long. We have a solid foundation to work." I plead as I gaze at him with hopeful eyes. He swallows before casting his eyes to the steering wheel for a moment. I hear him exhale quietly before finally returning to eye me carefully.

"Alright. I'm happy to give us a shot too. You know I've been pinning after you for years anyway." Yun answers with a small smile which causes the heat to rise to my cheeks again.

"Yun, so not the time." I grumble just as I start withdrawing my hands until he suddenly rests one palm over them.

"I mean it, I've been wanting to be with you for a long time." The earthbender utters sincerely and this time I find myself swallowing as my throat goes dry.

"Sorry to have made you wait." I apologise, it seems like it's the only thing I can say as I give him an apologetic smile. He laughs and drops his hand, allowing me to finally remove mine.

"Well, technically you were a taken woman back then, so you can hardly apologise for that." Yun quips with another wink. My chest tightens at those words and I give him a smile, forcing myself for it not to come out strained, but he spots it anyway and his smile drops.

"Oh gosh I'm sorry, that wasn't funny." He apologises as his face crumples with remorse, but I'm batting it away with a hand as if it were no big deal.

"No, you're fine. I mean, you're right after all. Anyway, I was thinking for tomorrow if you and Fuki swing by the house to help us pack and put it in the car to move into yours?" I say, changing the conversation. Yun realises, but doesn't comment further as he nods his head slowly.

"Yes, that sounds like a plan. I'll come by with my daughter at 11am?" He suggests and I nod my head as I open the car door.

"Sounds perfect. Thank you." I say with a smile as I close the door after me and move round the car to say goodbye. He pulls down his window as he jerks his chin towards my driveway.

"I thought you said your car was at the garage?" He asks cheekily as he gestures to my very present vehicle sitting perfectly untouched at my driveway. I flush in embarrassment.

"I mean...it does need to go to the garage." I mumble out a half-baked excuse, but the man's grin doesn't make me feel any better.

"I see, you just wanted us an excuse to talk. You know Katara, you could've just asked me out to dinner instead." Yun teases and I feel my ears go pink in mortification.

"Yun!" I hiss loudly as I get ready to turn away and stalk up to the entrance of my house, but a slender hand encircles my wrist before I can move. His thumb brushes against the inside of my wrist. My breathing catches in surprise, but he's withdrawing his hand before I can say a word about it.

"See you tomorrow, my fiancé." Yun whispers softly as he starts up the engine.

"Wai-" I start, but he drives off before I can finish my sentence.

My lips part as I stare at the quickly fading back of his car and I find myself stumbling backwards to rest against the brick walled fence outside our house. 'Shoot. That...made me feel something that I haven't felt since...my ex-husband. And I don't know how to feel about that.' I bite my lip hard at the thought and it takes me a good 20 minutes before I muster up the strength to enter my house. As soon as I step one foot into the apartment, a waft of Water Tribe cooking greets me. I plop my bag on the floor and shrug off my coat while kicking off my shoes.

"Mama's home!" A little voice shouts and I'm tackled into my son's familiar greeting. After I've returned the hug, I look up to find my Dad standing awkwardly just outside the kitchen.

"Hey, thought to cook something since it's late." Hakoda voices unsurely. I give him a tight smile and nod my head in thanks.

"I appreciate that, thank you. I can take it from here." I say politely as I stand to my feet. My father gets the message and quickly grabs his belongings. Yatsu glances between the two of us, like he always does whenever my father and I talk, but thankfully he never says anything. 'Part of me guiltily wonders if he thinks this is how children interact with their fathers. I seriously hope not.' I silently pray as Hakoda goes to give his grandson a hug.

"Be good for your Mum, Yatsu. I'll see you on Monday." My father voices quietly as he pulls back. His eyes flicker to mine and I give him another strained smile.

"Thank you for taking care of him while I'm at work. It's a big help." I say neutrally, prompting a sigh from the man.

"Well, I'm retired so it's not like I have much to do. Plus, seeing my grandson is the highlight of my week." My Dad says with a small smile. I nod my head and he takes that as his cue to leave. "Bye Katara." He says as he passes beside me. I sigh lightly before turning to face him.

"Yun and I are engaged, so you won't have to worry about picking up Yatsu from school all the time. We'll need to work up a timetable, but Monday should still be good for you to pick him up." I say casually. My father goes completely still, but he doesn't turn to face me.

"I...see. Congratulations. And yes, let me know what the new school run schedule is." Hakoda whispers before making his way to the door.

I watch him disappear with a sigh. 'I wish things hadn't become as fractured between us as they have, but it's hard to forget your father working with the man who killed your mother and for him to willingly allow my former husband get attacked time and time again. It didn't help that he never forgave himself for it, so now all our interactions are just stiff and awkward which is sad since our relationship has always been great. Even after Mum had died, we maintained a good bond until...my ex-husband disappeared. It kind of went south from there.'

I'm broken out of my thoughts when I feel a tug at my leg. I look down to see my son gazing at me curiously.

"You're already engaged Mummy?" Yatsu asks sweetly. I bend down and smile.

"Well, unofficially yes. We'll need to sort out some paperwork, but we're moving into Yun's house tomorrow. I hope that isn't too sudden?" I ask, suddenly worrying that I should've given him more time to mentally prepare himself, but I'm relieved when I see him shake his head.

"No point waiting! You won't know if you really like him untill we live with him." My son answers wisely and it's one of the few times where I find myself thankful that he's so mature for his age. I grin and pull him up in my arms as I stand up.

"You're my little wise one, you know that?" I voice softly as lean to give him a kiss on the cheek. He giggles and moves to return the gesture on my forehead.

"I love you, Mama. I want you to be happy." He murmurs as he leans his head against my shoulder. My heart skips a beat at his sweet words and I find myself tightening my arms around him.

"Thank you sweetie." I stutter back as I move towards the kitchen to finish off dinner for us.

Next Day:

I huff breathlessly as I grab all sorts of bits and pieces for both Yatsu and I to pack, but I didn't anticipate it being so much. I'm so focussed that when the doorbell rings, I almost jump off the staircase. I curse under my breath and rush down the stairs to open the door to reveal Yun and his daughter standing on the doorstep with broad smiles. I'm barely able to say two words before the girl rushes to give me a big hug.

"Oof." I say as she tackles me in a tight embrace.

"I'm so excited for you to be my Mum! I always felt you'd be the only one who could do the job." The 10-year-old girl babbles excitedly. I blink in surprise, feeling at a loss for words. Fortunately, Yun comes to my rescue and peels his daughter back.

"Fuki I told you, this is just a trial period. Katara hasn't signed up for anything yet. You have to wait to see if we get married before you can call her your mum." Yun explains firmly, before shooting me with an apologetic gaze, but I shake my head with a smile.

"No, no it's fine. I'm touched honestly." I intervene warmly, but the girl's shoulders remain slumped.

"Why do you have to be so negative Dad?" She mumbles and the maternal instincts in me can't stand to see her upset, so I pull her into a tight hug.

"Don't mind your Dad, you're free to call me whatever you're comfortable with." I whisper by her ear and that finally elicits a grin from her.

"Thank you Mum!" She voices cheekily. 'I thought I'd be better prepared for when she said it, but hearing someone other than Yatsu call me Mum is a lot more disorientating than I expected.' Again, Yun is quick to jump in.

"Fuki, I said no." My new fiancé orders tightly and the girl seems to drop it after that as she gazes at me awkwardly.

"Would Auntie Katara be ok for now?" She requests meekly and I internally sigh in relief.

"Auntie Katara is perfect." I confirm with a beam and my heart warms when she returns it.

"Alright Fuki, go and help Yatsu pack his things." Yun states with a smile as he rests a light hand on her shoulder. She turns to give him a brief grin.

"Ok Dad!" His daughter replies and dashes off to find my son. I wait until she disappears out of sight before turning to face the doctor.

"Thanks again Yun for coming to help." I murmur gratefully, but he just waves his hand nonchalantly.

"Not at all. I wouldn't be a very good fiancé if I didn't." Yun throws back with a smirk. I pause, still unused to the upgrade in our relationship. "Anyway, how far are you with the packing?" He continues on breezily. I swallow and allow my lips to twitch upwards.

"I've grabbed everything I needed to, just trying to pack it in bags is proving to be difficult." I admit as I lead him upstairs to my bedroom. I crouch down in front of the large suitcase as I try to push the contents down to zip the bag, but it's no use. The man chuckles as he goes to bend down beside me.

"You need to split it between other bags if you want to take all that." He points out with mirth. I purse my lips.

"And here I thought you were going to use some bending trick to compact everything in a single bag." I joke as the man gets to his feet to find more bags.

"You wish." He snorts back and disappears out of the room. I watch him leave and turn back to stare at my bag as a sense of deja vu overwhelms me. 'Shoot, I subconsciously said that because of that time with...'

I shake my head hard. 'No.' I order myself forcefully as I clench my hands tightly to bid away the thoughts of the Airbender. Yun pops his head around the door a few moments later with a couple of large boxes in hand. I chuckle.

"I'm not going to need all that." I joke as I take the top box from him. He rolls his eyes.

"I don't know why all ladies think they pack less than they actually do." The doctor retorts as he places the second box on the floor and starts picking up the top items from the open suitcase to put into the box. I purse my lips at him.

"And you're saying guys never overpack?" I ask with a dubious raised eyebrow. He shoots me a grin before looking back at the box.

"Nope. Have you ever seen a guy overpack?" At Yun's question I find myself automatically thinking about my ex-husband, but he was an Air Nomad, I assumed it was natural that he wouldn't pack much. 'Come to think of it, Sokka never really packed much either when we went out.' I blow a stray strand of hair from my eyes as I start sifting through my suitcase.

"Well, I've not been around too many guys to give it much thought to be honest." I admit with a half shrug, unbothered by the thought. My unofficial fiancé lowers the shirt he's holding in his hands as he stares at me.

"So, you really haven't been with anyone else? I assumed there must've been at least one other person before..." He trails off, being sensitive to my feelings. I sigh and shake my head.

"I didn't believe in multiple loves or anything like that. Just one person for life. Besides, I was more focussed on my studies than anything else. Never felt the need for relationships until...well, you click with someone and there's no going back from that." I answer ruefully as I plop some toiletry essentials in the box. The doctor cocks his head to one side.

"Mind if I see a picture of him?" Yun asks suddenly. I freeze before raising my eyes to meet his steady green ones.

"Why?" I ask cautiously.

"I saw him once as an inpatient but he was pretty banged up. It would be nice to know what the person who had your heart looked like." Yun says with a causal shrug, but his words have my breath catching as I look away from him.

"You assume I still have photos of him." I mumble as I grab a random item and plop it into the box.

"You don't?" His voice sounds more surprised rather than doubtful. I puff my cheeks before replying.

"I do." I admit with a sigh.

"So?" My fiancé prompts. I swallow.

"Do you have to?" I mutter, making him pause his movements.

"No, but I would like to." Yun replies honestly.

I chew my bottom lip for an age before getting to my feet and crossing the room to reach the desk drawer. I crouch in front of the one at the very bottom and pull it open. I pull back several folders before pulling out an upside-down frame just as I hear a whistle.

"Wow, you really hid it well." Yun comments from behind me. I snort.

"I didn't want Yatsu to find any." I say as I pass him the photo without glancing at it. Yun's grassy eyes flicker to the picture and he releases another whistle as he stares at the frame.

"Wow. He's actually quite the looker without all the bruises, cuts and black eyes." The man breathes out, almost as if he were mesmerised by the Airbender. "And those tattoos...we don't seem them often. Air Nomads are a pretty rare sight in the cities." Yun adds as he keeps his eyes glued to the picture.

"You almost sound like you're fawning over him." I utter dryly which finally prompts the older man to glance at me with a smirk.

"Jealous?" He asks with a quirked eyebrow. I snort.

"Hardly." I fire back with crossed arms. He unexpectedly waves the photo in my face.

"Look, he's standing all regal like. It's hard not to stare." Yun points out as my eyes accidentally fall on the Airbender's smiling face. Something jerks in my chest and I find myself pushing the frame away.

"He's always had that air about him." I say nonchalantly while Yun frowns at me.

"You didn't look." He mentions with a touch of amusement. I roll my eyes at him.

"I know the photo; it's mine remember?" I remind as I turn back towards my packing, only for the man to tap my shoulder.

"You still love him." Yun's comment almost steals the air from my lungs as I turn to face him slowly.

"I haven't talked to the man in years and things were strained for a long time even before then." I grit out, but Yun simply rests his cheek against the palm of his hand as his eyes flicker once more to the photo.

"You can have disagreements with someone and still love them." The earthbender points out lazily. I click my tongue against the roof of my mouth.

"I don't have any feelings for him." I say pointedly with hard eyes. Yun finally glances up to lock eyes with me.

"Then say his name." I splutter at his request.

"What?!" I yell, only to glance anxiously at the door, worried that my shout attracted my son's attention, but when I hear no patter of feet, I exhale lightly.

"I've never heard you say his name. That says a lot in itself." The doctor notes as he reaches forward to place the photo on front of me, but I stubbornly refuse not to look down.

"I need to put this away before Yatsu comes." I mumble as I reach for the photo, but Yun grasps my wrist.

"Take it with you." He murmurs softly. I go still at the request.

"Wh...what?" I echo back numbly. He moves to place the photo in my open hand.

My eyes accidentally fall on it once more. It was a picture taken after some official Avatar business, so the Airbender was all dressed up in his Air Nomad robes for the occasion. 'I remember how awkward he felt, but he had a cheerful charm to him and I couldn't help but snap a picture of him when he wasn't looking and then I had gotten it blown up to put in a frame.' My eyes linger on the photo, longer than I wanted to.

"Mummyyyy!" Yatsu's voice snaps me out of my senses and I immediately shove the photo under the suitcase before turning towards the door to find Yatsu running towards me, I catch him just as he trips.

"Yatsu? Honey, what's wrong?" I ask in concern as I spot dried tear marks on his cheeks.

"I can't find my favourite Pai Sho board!" He bawls out. I sigh as I rub his back. 'Ok, less drastic than I thought, thank the spirits.' I hoist him into my arms and stand up.

"Come on, I'll find it for you." I reassure as I glance behind him to Yun who's watching the entire exchange carefully. "Do you think you could get the last little bits? There's just my hair brush on the desk and..." I stop, flushing when I realise I was about to ask him to grab some of my underwear. "... actually I can do the rest." I say instead, but the man shoos me away.

"I noticed some clothes items were missing, I'm happy to pack them for you." Yun offers with a straight face. I shake my head.

"No that's not..." I start, but he stops me with a grin.

"Katara, we're doctors, remember? Some fabric isn't a bother." The consultant points out. I puff out my cheeks and give him my back.

"Fine. Just don't take long." I mumble as I exit the room with my son, trying not to look as embarrassed as I feel.

2 hours later:

Packing everything and driving to Yun's house took a lot longer than I thought it would, but I'm relieved when I hear that we're only a few minutes away from the house. I glance at the rearview mirror and my heart melts at seeing Yatsu's sleeping face as he rests his head on Fuki's shoulder. The girl in kind has her head resting on top of the younger boy's and they make the cutest pair.

"They kinda already look like siblings, huh?" Yun mentions as he glances at the rearview mirror before refocussing on the road. I smile and nod.

"They do, although siblings usually fight a lot more than they do." I say with a laugh. Yun joins in a moment later.

"That's true. Maybe that will happen later on." He voices with a grin as he makes a turn towards his house. When the car comes to a stop, Fuki wakes up with a yawn and with an excited grin she shakes Yatsu awake.

"Come on, we're here!" She gushes as she undoes her seatbelt and then reaches forward to undo Yatsu's, but with a surprised gasp she finds his is already undone. "Hey, when did you do your seatbelt?" The girl asks with wide eyes. Yatsu shoots her a big toothy grin.

"A minute before you did." He boasts, only for the girl to gaze at him in awe.

"I couldn't do my own seatbelt until I was 7 though!" Fuki replies, sounding semi-ashamed. I bite my lip when I hear that and turn in my seat, ready to intervene, but Yun places a hand on my shoulder and gives me a small head shake. I furrow my eyebrows at him before glancing back at the children.

"Mama's always teaching me things because she's so busy, so I have to learn quickly." Yatsu replies honestly as he goes to hold Fuki's hand. My chest tightens at that admission. "But thank you for trying to do my seatbelt, it made me happy." My son adds gratefully before he's enveloped in a hug by the older girl.

"You're so cute Yatsu." The girl coos as she pulls back to open the car door. "Come on, I want to show you my room! And your new room will be next to mine!" She chatters as she grabs the boy's hand and drags him to the front porch. I watch them for a moment before turning to Yun with a question on my face.

"How did you know that..." I start, only for the man to interrupt me with a knowing smile.

"I've watched their interactions enough times to know that your son has a really smart way with words. He's able to say exactly what the other person needs to hear. Honestly, some of the doctors could learn a thing or two from him." Yun replies honestly as he opens his own car door.

My lips part at that and I find myself watching my son as he runs after Fuki. 'Is that...true? Then how many times has Yatsu told me only what I wanted to hear and not the truth?' I wonder anxiously as I push open my car door and step out. I close it behind me and go to the boot to help Yun unload the baggage.

"Here, open the house door." The man requests as he throws me a house key. I catch it easily and look down at the key to find my name inscribed on the keychain. My lips part in surprise.

"Wait, is this mine?" I ask in disbelief as I watch him grab a box.

"Well, we have different shifts patterns. It would be a hassle if you had to borrow mine or if I had to wake you up at 6am in the morning to let me in. Thought this would be easier. It doesn't have to mean anything." Yun explains without meeting my eyes. My face softens and I hold the key tightly.

"That's sweet, thank you Yun." I murmur gratefully and something comes over me as I rest a hand on his shoulder and lean forward to press a light peck on his cheek. The man freezes at the gesture and when I pull back I find myself just as shocked. "Oh spirits, I didn't mean..." I start as I become more flustered, but the man releases a loud bellow which attracts the attention of the younger two.

"I'm all for more of those, don't you worry." The man says with a wink. I flush bright crimson as he hoists two boxes in his arms. "Now, mind if you get the door, before my arms drop off?" He teases as he bumps lightly into me. I feel the heat in my face and without another word I make a beeline towards the door.

"Mummy why is your face red?" Yatsu asks curiously as he tugs at my sleeve. The question has me flushing further.

"Yeah Auntie Katara, are you not feeling well?" Fuki asks as she goes on tiptoes to feel for my head. I catch her hand in mine and give her hand a reassuring squeeze.

"I'm fine you both. Just a little light headed from sitting for too long. Let's go inside, shall we?" I lie with what I hope is a convincing smile. Fuki seems to accept it willingly, but my son gazes at me seriously for several moments more before reaching out to hold my free hand.

"I love you Mummy." He whispers quite enough for only me to hear. I swallow and squeeze his hand.

"Love you too darling." I whisper back, past the lump that's made its way into my throat. 'That serious look of his, it almost felt like looking at...' I shake my head. 'I need to stop this.' I silently rebuke as I release Fuki's hand to unlock the house door. Yun is behind us moments later and I step aside to let him plop the boxes on the ground.

"I'll go grab the last few." I say as I swivel around to go back to the car, but Yun shakes his head.

"Follow Fuki, she wanted to show you something." Yun says instead and my eyes fall on the girl who's standing a little awkwardly. I smile at her warmly and go to hold her hand.

"Well then, show me what your Dad's talking about." I voice softly. The girl brightens up at that and tugs me into the house and there on the dining table is a huge chocolate cake saying 'welcome home.' My throat catches at the sight and I feel my lips tremble with emotion.

"You...got us a cake?" I whisper quietly, only for the girl to beam more.

"Nope! I made the cake!" She announces proudly. I release my hold on Yatsu's hand and without another thought, I pull the girl into a tight hug, surprising her as she releases a loud 'oof.'

"That's so sweet of you Fuki. Thank you so much." I utter gratefully as I rest my chin on the crown of her head. I feel her arms shake slightly as she returns the hug.

"I really want you to stay with us." She whispers softly. My lips trembles more and I find myself pulling her more closely towards me.

"I really hope so sweetheart." I murmur gently back. That seems to be enough, because she's pulling back with beaming eyes.

"Let me cut some for you both!" She announces as she dashes to the kitchen. I turn around to find Yun gazing after his daughter with a soft smile.

"Fuki is a really wonderful girl." I whisper to him. Yun grins at me.

"I can say the same about your son too." The man replies as he nods his head towards Yatsu who's helping Fuki hold the plates. I laugh at the sight.

"I think he just likes cake." I joke, but my eyes twinkle with a sense of pride regardless.

After we've eaten cake and had the grand tour by Fuki herself, the children sprint towards the toy room while Yun and I take the remaining boxes upstairs. When I set down the box and open it to start emptying its contents, I freeze at the first item. I whirl around so fast to meet Yun's gaze who's watching my expression with a satisfied smirk.

"Why did you pack this?!" I hiss as I point at the photo of my ex-husband that we were looking at earlier.

"Did you see what's under it?" Yun asks instead of answering me. I frown and lift up the frame to discover more photos. Lots of photos. Some of just the Airbender, some of the two of us, some of him with my brother and father and suddenly I feel nauseous.

"You went through my things." I accuse sharply as I glare at the man who's immediately holding his hands up defensively.

"You left the drawer open and my eyes landed on them, I couldn't help it, sorry. They're very cute photos though." Yun compliments without a hint of remorse. I narrow my eyes at him.

"What are you playing at?" I demand as my hand subconsciously clenches into a fist. He laughs at my reaction and moves to sit at the edge of the mattress.

"What do you mean?" The earthbender asks innocently. I grit my teeth and gesture to the photos.

"You're bringing photos of my ex-husband to your house that you've just brought your fiancé to, does that make any sense?!" I explain sharply. At this, his smile drops. He stares at the ground for several moments before sighing.

"Katara, I want you to talk to him." Yun whispers softly. I take a step away from him.

"What?" I echo back in disbelief.

"I know you told me he lost his memories, but I still think you need to talk to him. If it isn't to fix your prior relationship then it's at least to put a lid on it." Yun tries to explain, but I'm shaking my head confused.

"Why would you want me to talk to him? We're the ones getting engaged! He's not a part of my life. Heck, he's practically a stranger!" I argue strongly, but the man gazes at me sadly.

"Katara, your eyes soften every time you glimpse at his photo. And I'm not jealous if that's what you're thinking. I still have a soft spot for Fuki's mother. I always will. Just like you'll always have a soft spot for Aa-" I cut him off before he can finish his sentence.

"Don't say his name." I order harshly which elicits a sigh from the doctor as he leans back from his perched position on the bed.

"My point is, we're not trying to replace anyone we love. We're just... trying to find a new place to love from. The difference is...my wife is dead. I can never talk to her, no matter how much I long to. You however, you can still talk to him if you want. He might not remember you, but at least you can tie things off the way you want to. And I wouldn't feel offended if you wanted to get back together with him, I respect that. But I don't want you marrying me while harbouring unresolved, unconscious regrets." Yun urges earnestly and I bite my lip hard.

"That's an odd thing to say from someone who wants to marry me." I mutter with a touch of bitterness, but Yun's expression is unwavering as he rises from his seat to cross the distance between us as he takes a hold of both my hands.

"I want us to go into this with no regrets. I've tied off what I needed to and I feel you should do the same. Otherwise it will affect our relationship going forward. I know I'm asking a lot, but please talk to him. Not just for your sake and mine, but also for Yatsu's." I flinch when he mentions my son's name and the doctor notices almost instantly.

"Oh. He...doesn't know...your former husband I mean." Yun's voice is halted and unsure. I dart my eyes to the side.

"He...lost his memories before I found out I was pregnant. I didn't see any point in telling him." I confess quietly. Yun inhales sharply as he bounces back and forth on his heels.

"That could... complicate things." The man's voice is subdued, almost lost in thought.

"How so?" I ask with a quirked eyebrow as I watch the earthbender chew his lip.

"If he finds out he has a son, he'll likely want to be involved which makes things harder for us, especially if the two of you choose to stay apart." My fiancé explains as he locks eyes with me.

"There's no if, I'm not getting back together with..." I start strongly, only for Yun to shake his head.

"Love crops up when we least expect it, especially in places where it once was. You had a son with him, Katara. You can't sweep that under a rug." The man utters firmly and hearing it said so bluntly makes me feel so exposed and vulnerable.

"Yatsu wasn't planned. I told you things between us were strained, it was a one-night thing and..." I'm stopped by Yun's hands moving to rest lightly on my shoulders.

"Katara." I go still at hearing my name and after an age I drag my eyes up to his.

"Yes?" I mumble as I feel the tips of my ears going pink.

"You don't have to explain anything to me. Besides, planned or not you love that boy to death." The doctor voices gently and I find my lips trembling.

"I just...don't want him to know that he wasn't wanted at one point." I confess as my eyes prick with tears. The earthbender's arms move to rest across my shoulders in a loose hug and I find myself leaning forward until my forehead rests against his chest.

"He doesn't need to know that." Yun says in a quiet hush as he rubs the backs of my shoulders. With his ministrations I find my trembling slowly ebbing away. "Whether you tell your ex-husband about Yatsu or not isn't my business. The only thing I ask, is that you talk to him. Say whatever you need to, to allow yourself to move on or re-orientate yourself. If after that, you still want us to get married then we will. And while you find the courage to talk to him, we'll continue this living arrangement. How does that sound?" Yun suggests gently and with a resigned sigh, I nod my head.

"Alright." I agree reluctantly. Just as I pull back, I feel soft lips pressing into my forehead before retracting. My heart skips a beat as I stare up at the man who gives me a cheeky grin.

"That's for the surprise kiss earlier." He teases as he pulls his hands off my shoulders slowly. I blush and push him back.

"I think we need to set up some boundaries." I mumble as I clutch my elbow insecurely. The man's eyes twinkle with mirth as he slides his hands into his pockets.

"Your wish is my command, my lady. What would be your first rule?" Yun jokes and when I reach out to punch him, he takes it like a champ.

"Don't call me that." I mumble as I cross my arms over my chest.

"Still awaiting your rules." Yun prompts, almost sounding excited for whatever reason. I eye him curiously, but his expression gives nothing away.

"Well, we already know we're sleeping in two separate rooms. I think we should come up with a bath schedule too to avoid any...awkward run ins." I voice, trying not to sound too flustered, but by the grin on the earthbender's face, I can tell I'm failing miserably.

"I'll make sure to knock whenever the door of your room is closed, of course. What about touch, any particular rules?" Yun asks innocently and I feel like punching the man again, but I refrain with clenched fists.

"Cheek and forehead kisses are...ok. Hand holding too and erm...hugs." I list off sounding like an absolute child and wanting the floor to swallow me up right this instant.

"So, I guess it would be too soon to do something like this." Yun breathes out as he stretches his hand to take a hold of my chin. His thumb brushes over my lips, stunning me into silence while my heart thumps against my ribcage. I respond after a delayed moment to push his hand back.

"Much too soon." I grit out as I take a step back, but the man gives me an embarrassed expression.

"Sorry, I shouldn't have done that. It's been a while since..." Yun trails off with a cough as he rubs the back of his neck, looking apologetic and suddenly I feel bad.

"No it's...it felt nice." I confess with tinged cheeks, making the man visibly brighten. "But it's too soon for me. Sorry." I add awkwardly, only for the man to smile at me warmly.

"Just lead me by ear. I won't start anything you don't want." Yun replies sincerely and I find myself relaxing once more.

"Thank you, Yun." I murmur gratefully. The man beams back.

"Brilliant, I'm glad we got that out of the way. We'll draw up a school run chart later, but for now I'll leave you to unpack. There's hot water too so you can take the first bath if you like. And Yatsu too. Fuki usually takes hers in the late evenings and I'll take mine later." Yun rattles off as he makes his way to the door. I nod my head in appreciation.

"That sounds great, thank you so much. We're looking forward to living with you and your daughter." I answer honestly which causes Yun's face to soften.

"As are we." The man replies gently before leaving with a wave. I watch him until he disappears before turning to stare at the pile of photos with a sigh. 'First Sokka, now Yun. Why do they think talking with him will solve anything? Won't it make things worse?' I question sourly as my eyes linger on the photos before slamming the box shut.

"I'll start with the other box." I mumble to myself.
