Original Asy and Furg/Star belong to Furgemancs

Original Ink belongs to Myebi/Comyet

Notes: I started this AU idea being influenced by Big Brothers Big Sisters of America. They match kids with young adult mentors. Four times a month, they hang out together doing anything from studying to playing sports. This program lowered the possible drug use and possible chance of jail time for a lot of kids, allowing them to have a better future! I wholeheartedly support them! Also, Undyne's fraterity is in no way a nod to monster university. just a coincidence. Also, as requested by Sugar's owner, he will not be making any appearances. Also to note because it wasn't mentioned in story. Cooler also studied to be a nurse. That course of study wasn't his major though.

One Year Later, Cooler's POV

I close the door behind me as I enter the house. Today...was...was tough. I go into the kitchen and grab a soda. Part of me wishes I was the kind of guy to drink, but it's only a small part of me. If I let this drive me to drinking, I'll never stop...I know that for sure. I go to the living room and sit on the couch. Hunched over, I stare at my feet. I...I should feel more, right? I mean, I had been helping the family for most of the past year. They were like family to me...Shouldn't I be feeling more than just...just empty? Sleet! I can't even bring myself to cry over it! I...I felt so detatched...lost. Then, arms gently wrap around me. I smile a little, already knowing who's arms they are. "...hey...you're home early, Aly" I say.

"Yeah, got sent home early, but we can dicuss that later. Are you alright, Sans?" Alyssa asks. I look up at her. "...I...I don't know..." I say and look down again. Aly sits next to me. "Did something happen at work?" She asks, her hands gently holding mine. "You...you can say that..." I say and she nods. She's currently in her Masic form, which I briefly find strange because she was in it when she left this morning. "Did you stay in Masic form all day?" I ask. Alyssa frowns. "We'll talk about me later. Let's get through this first" She says and I nod. "...I...the family I...I work with...the son passed away today..." I say.

Aly frowns and hugs me gently. "I...I'm so sorry, Sans...Ian was such a sweet boy." She says and I nod. "He almost looked like he may have pulled through...at the end...but..." I trail off. Tears that refused to come at the home or when I was here alone, started to trickle down my face. "The worst part was that...that i couldn't bring myself to feel anything while I was there...yeah, I could tell them I was sorry for their loss, but it felt...it felt..." I trail off again. "It felt hollow, right?" Aly asks and I nod. "It's shock, Sans. Ian was your first patient that you have lost. Everyone that does the work we do, experiences it at some point..." Alyssa says and hugs me a little tighter.

Alyssa's POV

I come downstairs when I heard the door close. 'Sans must be home.' I think and go to the kitchen. "Welcome home, love" I say and frown as Cooler just walks past me. 'he's never ignored me before...something's wrong' I think and watch him get a soda from the fridge. He looks at it a moment before putting it back in the fridge and closing the door. 'Ok, now I know something is wrong. He always has a soda after work' I think and follow him to the living room. I frown as Sans drapes his arms over his legs, hunching over to look at his feet. I slowly walk over to him, not wanting to startle him. When he doesn't register that I'm in front of him, I gently wrap my arms around him.

"...hey...you're home early, Aly" Cooler says with a small smile that doesn't last long before the frown is back. "Yeah, got sent home early, but we can dicuss that later. Are you alright, Sans?" I ask worried about him. He looks up at me. His one eyelight is trembling, on the verge of tears that refused to come. "...I...I don't know..." he says and looks down again. I sit down beside him, trying not to crowd him. "Did something happen at work?" I ask gently taking his hands in mine. "You...you can say that..." he says and he looks at me a little confused. "Did you stay in Masic form all day?" He asks and I sigh. 'One problem at a time' I think.

"We'll talk about me later. Let's get through this first" I say and he nods. "...I...the family I...I work with...the son passed away today..." Cooler says and frown, hugging him gently. "I...I'm so sorry, Sans...Ian was such a sweet boy." I say and he nods. Cooler and I both interacted with Ian and his family. Ian was bedridden with advanced Leukemia. It has been a hard road, not only for his family, but us as well. Cooler especially was close to Ian, and managed to make his days bright, either with jokes or ice sculptures. "He almost looked like he may have pulled through...at the end...but..." Cooler trails off as tears start to trickle down his face. I hug him again, wishing I could ease his troubles.

"The worst part was that...that i couldn't bring myself to feel anything while I was there...yeah, I could tell them I was sorry for their loss, but it felt...it felt..." He says, his voice cracking up in sobs. "It felt hollow, right?" I ask and he nods. "It's shock, Sans. Ian was your first patient that you have lost. Everyone that does the work we do, experiences it at some point..." I say hugging him a little tighter. I briefly think about my news...'Rebirth...renewal...why must it always come at a price?' I think. "Don't feel sad, love" I say making him look up at me. "Feel happy that he's no longer in pain. That he is free at last. That's what I tell myself" I say and Cooler smiles through his tears.

"So..." Cooler says wipping his tears away with his sleeve. "Are you going to tell me why you got sent home early?" He asks cheering up a little. I smile a little, and take his hands again. "Well...I am going to be stuck in Masic form for some time, and I can't use my healing or soul magics. I can give examinations, but no use of magic" I say and Cooler looks worried. "Total magic lockdown...that's not something to be taken lightly, Alyssa. Are you alright?" He asks taking my hands in his. I smile. "Of course I am. The baby and I are fine, Santious" I say and count the seconds before he realizes what I just said. One...two...three... Is as far as I get before Cooler hugs me. "Alyssa! A baby! We're going to be parents!" He says, a huge grin plastered on his face.

"Does anyone else know?" He asks. "Just my department at the hospital." I say. He nods, practically bouncing in his seat. 'He's so adorable, the big dork' I think. "So, how far are you?" Sans asks, still smiling. I giggle. "Two months." I say and he nods. "Seven left to go, right? I'm not an expert on the Masic form." He says and I nod. "Nine months all together for Masic. For Dual souls, Masic is the best form to be in. It has the highest success rate. The baby can still be born a skeleton, it's just safer for both the mother and child" I say and he nods. "So, how are we going to tell Father?" He asks and I smile. "I have the pictures from the Ultrasound they did. Could give them to him tonight as a birthday present." I say, reminding Cooler that Gaster's birthday is today.

Cooler smiles and I show him the pictures. "We won't know until he or she is born what gender they will be. I do know that they're going to be a skeleton though." I say and Cooler nods still smiling. "That will be a perfect gift for the old man. Better record his reaction though. It's going to be hilarious" Cooler says. I nod and we sit there for a few minutes. "Are you sure that you are alright?" He asks and I nod. "I'm sure. I've been home about a couple hours now. I'm rested, Sans." I say and he nods. "Welp, the party is soon. Best get ready to go." Cooler says getting off the couch. I nod and get up as well.

After a half hour of getting ready, we head to Alex's resturant, where the party's being held. I'm wearing a loose and comfortable pink sweater, my scarf, a pair blue slacks, and comfortable sneakers. Cooler's wearing his usual outfit as we come in. I'm holding a small box. We decided to stop by the clothing store for one more thing to finish up Father's gift. "Hello Father" I say and he smiles. "Hello, alyssa, Santious. It's always good to see you. I missed you" Gaster says and I giggle. "You saw us this morning" Cooler says shaking his head. "So? I can still miss my children." He says. "Is Papyrus able to make it this year?" I ask.

Gaster sighs. "Unfortunately, no. He wasn't able to get any leave from the Royal Guard, but he sends his love." Gaster says. "He certainly has come a long way." Cooler says and Father nods. "Indeed. I'm so proud of him. He has shown promise in both healing and blue magics. So, he's getting training as a Search and Rescue Officer for the Royal Guard." Father says. Soon, Asgore and Toriel join us at the table. "Sorry, Asriel and Chara were unable to make it. Chara hasn't been feeling too well as of late." Toriel says and we nod. "I do hope she gets better soon" I say and they nod. We order our dinners and the waiter takes back the menus.

"So, gifts while we wait?" I ask and Father nods. "Open everyone else's first. We want to save ours for last." Cooler says and Father nods. Cooler smiles and starts to record. Gaster looks at him. "Why are you recording this?" He asks a little annoyed. "It will make sense in the end" Cooler says and Gaster nods. Toriel got him a new mug. Asgore got him a set of golf clubs, saying that now he doesn't have an excuse not to play with him. Papyrus sent Father a hand carved figure of a gaster blaster. I smile and hand him the one from me and Cooler. "This is from me and Cooler" I say and he nods. "I assume this is why you are recording this?" He says. "Yup." Cooler says as Father unties the bow and sets the lid aside. "What? What is this?" Gaster says holding up a black T-shirt. "Read it out to us, Father." Cooler says.

"Papa, Because "Grandfather" is for old guys" Gaster says and then his eyesockets widen. I giggle. "There's more in there" I say and he sets the shirt aside. He takes out the pictures. "This...this is real, isn't it?" He says looking at the pictures. I nod. "Found out today, actually." I say and he smiles, trying not to cry. He hugs me and I laugh. "So, how far along?" Toriel asks with a kind smile. "Two months. I'm restricted to clinical exam work until the baby comes, but that's fine. Spent a couple hours notifying my patients of the change, but no one's upset about it." I say and she nods. "We won't know the gender until birth since the baby will be a skeleton. The baby also has a normal skeleton soul. So, the baby will only have one form, like Santious." I say and they nod.

The party ends on a happy note, and I head home with Father and Cooler. "I will have to say, I wasn't expecting your gift." Father says when we get back home. "To be honest, neither was I" Cooler says and I smile. "Yeah, I know we wanted to wait a few years, but life happens...a cycle of birth, death, and rebirth..." I say trailing off. They look at me concerned. "Are you alright, Alyssa?" Father asks. "Oh, yeah, just a bit tired. I'm going to bed" I say and go upstairs. "Good night, Aly. I'll be up in a bit" Cooler says.

Cooler's POV

I watch Alyssa disappear into our bedroom upstairs. "She looks exhausted" Father says and I nod. "It's been a long day for us both. We lost Ian today" I say and Father nods. "I'm sure he's happy wherever he is now." He says. I nod and go into the kitchen. "It was the first time...that I saw someone die...someone I was close to." I say grabbing a soda. "It happens to us all. The only way to not hurt as bad is not to get attached to your clients." He says and I nod. "Yeah, but...I can't do that...close myself off from others. I never have been" I say opening the can. "Then, you must be strong, for yourself, Alyssa, and the families you help." He says and I nod.

"I'm so excited about the baby...Alyssa seems happy too. I...I just hope I'll be good enough" I say and Father nods. "That's perfectly normal, Sans. I felt the same..." He says. "Father?" I say as he sits at the table. "Your mother and I...we tried so many times for you...So many heartbreaks...We almost gave up." He says and I sit beside him. "I...I just want you to know that it's in your family history for weakened souls., and to be prepared for whatever pain and sorrow may come." He says sadly. "How many times, Father?" I ask. "Five...the last two...they were almost fully formed...we watched them turn to dust." He says and I hug him. "After you, however, It was easy to have Papyrus. We never understood why." He says and I smile. "Because your souls already knew what to do, I'd bet" I say and he smiles. "Probably." He says with a small smile. About an hour later, after some more talking about the baby to come, I say goodnight to my Father and head to bed. I smile looking at Alyssa as she slept. She looks so peaceful. I change into some sweats and a t-shirt before carefully climbing into bed so I don't wake her. I fall asleep with a small smile.

Alyssa's POV

Dream Start

There was fighting...fighting all around me...and death. I could smell it in the air as I ran for cover, any cover to hide me from the humans. "Senara! Senara, where are you?" A voice yells over the sounds of fighting. My eyes widen and I look around for my lover. "Vale! Over here!" I yell over the battle, catching his attention. Vale runs over to me. My dreaming mind briefly notes how this Vale looks exactly like Santious. Vale holds me close. "Sen, you had me worried sick! I thought...I thought the humans dusted you!" He says, holding me tight to him. I cry, gripping his cloak. "Vale...it's...it's too much...too many...so many souls...This has to stop...I...I don't know how much longer I can take all of the souls that need to be reborn...My soul hurts..." I say.

He frowns. "I'm here now, Sen, don't worry. We'll make it through this, I promise" Vale says as he tries to get us through the battlefield. I whimper in fear as magic, spears, and arrows fly over our heads. "Vale...we're trapped..." I say scared. "We can't give up. Not now that we're so close." He says and uses his magic to freeze several humans solid so we can pass. "Please forgive me, my love. There's no other way" He says as I cry for the lives lost. Suddenly, a skeleton joins up with us, but he looks nothing like any of the skeletons we know. "Stay back, stranger! We don't know you and I don't trust you" Vale says pointing his saber at the new skeleton. The skeleton makes no move to get closer as he looks around.

"Underbattle...This place always depresses me. The perpetual, never-ending battle. The stentch of death and dust...I could never understand why a creator would make a world like this." He says. I tug on vale's sleeve. He looks down at me. "What is it, Sen?" He says. "I don't think he's here to hurt anyone." I say, making the new skeleton look at me. "Who? Me? Of course I'm not! My name is Ink. I'm the defender of the Multiverse!" He says striking a pose. We look at him confused. "Oh...yeah, you don't know anything about the multiverse since your AU is so new." He says and comes a little closer. Vale has me stand behid him, protecting me. Ink stops a moment. "You don't really trust anyone, do you?" He says.

"Not a chance in hell. Especially since we only just met. Senara may think you're good, but it takes more proof for me to see it." Vale growls at him. Ink nods. "I think I understand this world a little better now. It's supposed to be a tragic romance world." He says. "What the hell are you going on about?" Vale says. "You can't save her" Ink says making Vale angry. "What the fuck did you say?" Vale says. "I've been here a few times. This world has reset multiple times. Although, this has been it's longest run since a reset. Which leads me to believe that the reset of this world is tied into her life." Ink says pointing a brush at me. 'How...how could he know that?' I think Vale's eyesockets narrow.

"Buddy, you better start making sense before I cut you down where you stand." Vale says as the winds pick up. "Vale, please, calm down" I whimper as the cold winds bite at my bones. He looks down at me and his eyesockets soften. "Sorry, Sen...are you alright?"He says as the winds die down again. I nod. "I'm alright." I say before we hear a loud explosion from the other side of the battlefield. Ink frowns at the explosion. "Seems like Error finally found this place. It's no longer safe here..." Ink says. "Like it was safe to begin with?" Vale says. "Hmmm good point." Ink says as my soul starts to hurt even more. "Sen? Senara? Are you alright?" Vale says as I drop to my knees.

"...so many...so many souls..." I say, tears streaming down my face now. "Error must be killing everything...I thought we had an understanding...unless..." Ink trails off. "Hey, Bonehead! Unless what?" Vale yells at Ink while trying to look after me. "Unless the creator of this world decided to start this AU anew...A new story...A new start...everything. It happens from time to time. A creator decides they don't like the world that they have made, and rewrite it's story. I've seen this before." Ink says. I see it before Ink or Vale do...A strong blast of magical power, probably the combined Monster forces behind it. It takes everything in me to knock Ink out harm's way. "SENARA!" I hear Vale yell as my body writhes in agony from the blast.

Vale rushes to me and holds me in his arms as tears go down my face. "V-vale..." I say weakly. "Don't...don't talk...save your strength, Sen. You're ok...You'll be ok" Vale says trying not to cry as Ink watches us. When I look at him, he seems to be looking at some kind of box that's floating in the air. "Do not worry. You and Senara are very loved by your creator. You will survive to the new AU" Ink says. Everything around me seems to fade to white as I barely make out Vale yelling. "SEN! SEN please wake up! Please!" He yells, but I can't answer him...I don't feel any more pain, but for some reason, I can no longer move.

"Do not worry..." A voice says in the empty, white space. "You will find each other again, Senara" It says again. "W-who are you?" I ask. The voice giggles a minute. "I'm your creator." The voice says. Then...everything goes quiet...and stays that way for so long that I lost track. After what seemed like an eternity, I noticed that I was becoming a child again. This normally didn't bother me since I knew about how resets worked. However, my soul began to change as well, from a simple rainbow soul to a soul that looked like a monster and a human soul smashed into each other, both of them rainbow.

Dream End

I wake up to Sans trying to wake me up. "Alyssa! Aly, please wake up! Please!" He says and I open my eyes with a yawn. "Santious...what...why did you-" I am cut off as he hugs me tightly. "Thank goodness, Alyssa!" He says and I can tell that he's been crying. "Santious...why are you crying?" I ask confused. "You...you almost died on me, Aly!" He says and I stare at him dumbfounded. "What?" I say. "You wouldn't wake up this morning, and then your soul started to crack. You're lucky Cooler got you to the hospital when he did." Doctor Sweets says. "I'm putting you under observation and bed rest, here in the hospital." Sour says and leaves.

To be continued...
