It was a week later and it was the day Chuuya was supposed to return from Russia. Well the team he had gone with had told Dazai that Chuuya had returned to Yokohama, but that he had jumped out somewhere downtown, and summoned the Black Lizard Squad, Akutagawa and Atsushi, with not a word to Dazai as to what he was doing.

Dazai was currently sat in his office, Kyoka and Demon Snow outside his door, acting as bodyguard. He had a headache, firstly he had less than three weeks until his heat, and was trying to convince himself to visit Ranpo, as his husband Poe was on house arrest, Dazai would have to see them at home. He didn't think he would have much success asking Ranpo to father his child, but the man never ceased to surprise him. Secondly, a new group headed by a Fyodor Dostoyevsky were threatening to upend this peace he had worked so hard to achieve. Yes there were small spats, but this, if what Dazai had heard of the man's plans were true had the possibility to destroy the Mafia, Armed Detective Agency and leave Yokohama in ruins. Fyodor had been in Yokohama for two weeks, and Dazai's intel had told him he had planned to attack within days of landing, but something had stopped him, and Dazai was afraid of the reason why. The man was after The Book which Dazai knew for a fact was- his thought was interrupted by a disruption at his door.

"Let us in Kyoka." It was Chuuya's voice

"But Dazai said no visitors."

"Let them in!" Dazai yelled back.

Chuuya entered first, a man with long dark hair followed behind him. He was wearing a white outfit, and a cloak. Akutagawa followed behind them and was using Rashomon to tie the man's hands. They stopped in front of Dazai's desk, Akutagawa wrapping Rashomon around the man's legs as well.

Dazai was silent for a few seconds as his brain rebooted from the man's scent. He smelt gorgeous.

"Chu…ahem Chuuya, you know prisons go to the cells, why have you brought this man-"

"Fyodor, Fyodor Dostoyevsky" The man supplied

"He's a wanted criminal Chuuya! Why is he in my office?" Dazai's head was starting to feel fuzzy from Fyodor's scent, he took a drink of water to try and clear it.

"Tell him." Chuuya turned to Fyodor.

"Your him aren't you? The man from the nightclub all those years ago, my mate."

"So what if I am, you came to my city to destroy it!" Dazai yelled, choosing anger over the fact all he wanted to do with kiss Fyodor.

"But I didn't, your scent permeates all of the underworld in this city, I couldn't think straight from the day I landed, all my plans crumbled when I realised I could have you."

"The men he was working with were all captured by Ango's team. The threat has been eliminated Dazai" Chuuya told him.

"Will you give me a baby?" Dazai asked Fyodor

"Well, one day maybe? We barely know each other I can't have a child with a man I barely know."

"The choices were Yes or No. Pick wisely or you'll be following your men to prison, and that prison is not pleasant" Dazai growled, Fyodor's scent was settling into his skin, and much to his surprise he could feel the first signs of his heat starting. It wasn't due for another three weeks.

"Maybe! Court me first. I don't care if you smell amazing I want to learn to love the man behind the scent, and I will not consider fathering our child until we've done that." Fyodor had waited so long to meet his mate again, he didn't want to lose the opportunity. Dazai could feel his pants getting wet from slick, he stood up quickly, his face was flushed and he just knew the others in the room knew he was going in to heat.

"Fine! Chuuya take him to the cells, I'll deal with him another day," and with that he stormed out of his office, slamming the door behind him.

It was one of the worst heats of Dazai's life, his body was craving his mate and he was too stubborn to go and get him. When his heat finally died out, and he'd slept it off, Dazai was in a much better frame of mind. He texted Chuuya to meet him at the garden in thirty minutes and to take him to wear he had locked up Fyodor. He cleaned himself up, put on a fancy shirt and jeans, and made his way to the garden, he picked a small bouquet of daisies and wrapped them with a dark purple ribbon. As he finished Chuuya appeared.

"I put him in the nicer cells, you know the one with a bed and toilet, rather than the ones with the shackles"

"Thanks Chibi."

They made their way to elevator, getting on together

"By the way, what got into you the other day? It's unlike you to strop out of a room like that."

"His scent overwhelmed me, I went into heat, it wasn't due for another three weeks."

"Oh wow, he's must really be yours then."

"Hmm, I'm going to court him and woo him so hard, he'll have no reason not to father my child, and spend his days with me or…" Dazai trailed off, a goofy smile on his face. The elevator pinged at the floor and Chuuya led Dazai to Fyodor's cell. Chuuya was silently thanking himself for finding some clothes for Fyodor, they didn't quite fit, but he was decent enough to go on a date with Dazai. Once in front of the cell Chuuya handed Dazai the key and left,

"Firstly I'd like to apologise for my behaviour the other day." Dazai greeted him,

"Accepted, I guess it would be a shock to your system. Your friend told me of your err quest to have a child."

Dazai blushed, "If I'd known we would meet again I would have waited, oh!" Dazai suddenly remembered the flowers in his hand, "These are for you, I'd like to take you on a date today."

"I'd like that" Fyodor smiled, "Do you mind if we set some ground rules before we begin?"

"Sure."

"I will not mate with you in heat until we have had sex outside of it. If I do not feel ready to father our child when you are in heat, I reserve the right to take the alpha pill."

"Yes, to point one, no to point two, if you aren't ready, you do not come near me whilst I am in heat."

"Acceptable,"

"I have some – neither of us will pry if the other is uncomfortable sharing details of their past, and as a recent enemy of my organisation, you will be given the flat opposite mine, so I can keep an eye on you. We are the only ones on that floor, but until you have proved yourself trustworthy, you will not be able to go anywhere without me or my approved guard. The elevator on my floor is key operated, and you will not have one."

"Harsh, but fair. Anything else?"

"Not that I can think of right now, but these can be added as our relationship progresses."

"Deal," Fyodor smiled,

Dazai unlocked the cell and took Fyodor's hand, leading him to the elevator. They spent the day shopping, as Fyodor only had the outfit he had been captured in, Dazai bought him a few outfits, pyjama's and some toiletries. They ended the day in a fancy restaurant. They found as they talked, they had a lot in common, both were far too intelligent for their own good, but together they were equals. They cwtched goodnight at their respective doors, Dazai not quite ready to kiss him.

It was May and they had been dating for two months. Dazai and Fyodor's relationship had grown steadily. Dazai had decided that Fyodor wasn't a threat and had allowed him more freedom, he wasn't allowed outside alone, but Dazai often found him in the garden covered in dirt, but content. Despite Fyodor expecting a long courtship he had found himself in Dazai's bed a month and a half after they met, and they were preparing to spend their first heat together.

Dazai had never realised a heat could feel so loving and tender, Fyodor's scent smelt like a nice cosy hot chocolate to Dazai and being enveloped by that during his heat was the best he had ever felt. Following his heat, they were more touchy feely together, Fyodor spending more time at Dazai's flat, and in his office when he wasn't working on anything confidential. Then the time came for Dazai's pregnancy test. They both felt quite hopeful as they sat, hand in hand in Yosano's office. She had the results of Dazai's test in front of her, her voice quiet when she started

"I'm so sorry Dazai, you're not pregnant."

Fyodor pulled Dazai in for a cwtch, wiping the tears that were forming in his eyes,

"There's always next time Dazai."

Dazai pulled away, and stood up.

"No! I played the game. I did the work. He is my mate. What are you hiding?" Dazai yelled, he knew he should feel ashamed for the way he was acting but he didn't care,

"Dazai calm down," Fyodor tried to touch him to calm him down.

"Don't touch me! You promised me a baby, why? Why not?" Dazai's voice faded as he sat back down, tears falling.

"Take a deep breath Dazai." Yosano told him as she handed him some tissues. "Better?"

Dazai nodded,

"I was a bit confused as well, so I brought Fyodor in for some additional tests. Have you had your fertility screened before Fyodor?"

"I don't think so."

"You have low fertility Fyodor. It doesn't mean that you will never have a child, it's just going to be difficult."

"I'm so sorry Dazai," Fyodor turned to Dazai,

"Why are you comforting me, it's your body that's rebelling I should be comforting you."

"What are our options, is there anything I can do to help increase it?" Fyodor asked

"If you were both beta's we could do IVF, but an omega's body does not react well to the procedure. How frequent are your ruts?"

"Ummm I had one after I presented, on my fifteenth birthday, but I haven't had one since."

"Hmm that's going to make it more difficult, usually an Alpha's fertility increases during their ruts, it's rare for them to coincide with a heat though, and if yours are so far apart, never mind, we'll drop that idea." She paused, "I'm sorry I can't help you, but honestly, there's nothing to say that luck won't be on your side next time Dazai's in heat, so I would keep trying, keep coming in for a test at 4 weeks, and we'll go from there."

Dazai just nodded, afraid to speak as his mind was a swirl of heartbreak and anger.

"Is there anything else you need us for today?" Fyodor asked

"Nope, I'll see you again in a few weeks." She paused, "and remember Dazai, you are not alone, don't get lost in the emotions. Talk to one of us."

"I'm fine." He didn't sound it, but Yosano knew it was a lost hope, she just hoped that Fyodor would help him. They left Yosano's office, and Fyodor pulled Dazai in for a cwtch or tried to

"Get off me." Dazai snapped at him. They entered the elevator together, Dazai pressing the button for their floor.

"I want your flat today, I don't care where you go." Dazai told him.

Fyodor pressed the button for the garden, "Okay, I'm just going to stop in the garden then I'll be up, okay?"

"Fine."

The doors opened and Fyodor got off.

He returned to his flat twenty minutes later, hoping he had given Dazai enough time. He had a small bouquet of daisies and sweet peas in his hand, as the elevator opened onto their floor, Fyodor could hear classical music coming from the door to his flat, it had been left ajar. He quietly pushed the door open, and stopped, taking in the scene. The kitchen and his bed had been covered in a paint spattered sheet, and Dazai was in the back corner working on a large canvas, half of it was the colour of anger, the other sadness.

When Fyodor had moved in, he had noticed the canvases and art supplies in the top corner of his room. Dazai had apologised but made no attempt to remove them, so Fyodor had avoided the area afraid of damaging the artworks that had been left behind. The song that had been playing stopped, and silence filled the room, Dazai stepped back from the painting, and turned to the door. He jumped, dropping his paintbrush when he saw Fyodor in the doorway.

"Fedya, how long have you been there?"

"Just a few minutes, the painting is beautiful Dazai."

"Thank you," Dazai blushed, "I…I have had some unhealthy coping mechanisms in the past, but painting helps side track me enough to let go of wanting to use them."

"Do you want me to leave? I'm guessing someone being here probably doesn't help you."

"Hmm no… no it's okay." Dazai noticed the flowers in Fyodor's hand, "Do you want me to move the sheet so you can get a vase for them?"

"Oh, they're for you, they reminded me of our first date, well the daisies did, the sweet peas were just pretty."

"They're lovely Fyodor," Dazai paused, thinking for a moment, "Can I paint you? Next to the arched window, I'll sit you on the floor with that bouquet in your hands."

"Sure" Fyodor smiled, having his painting done sounded like torture, he had never been a fan of pictures of himself, but Dazai looked so excited Fyodor didn't want to say no.

"Perfect. Stay over there whilst I set up,"

"Do you want a drink? I'll make them in your flat,"

"Make a pot of tea please. There's a melamine tea pot in the top cupboard, it's the one covered in paint, I knocked a proper one over and smashed it everywhere so plastic seemed like a good idea" Dazai smiled.

When Fyodor returned with the tea, two sandwiches and some biscuits for later, Dazai had moved the cloth covering the floor so Fyodor could sit next to the window and had setup a small easel and canvas, paints and various art supplies surrounding him. Fyodor placed the tray between them, but off to the side where it wouldn't get in Dazai's way.

"What pose would you like?" Fyodor asked

"Hmm cross legged, cradling the flowers in your arms, like this" Dazai got up took the flowers and modelled the pose for Fyodor. "If you get uncomfortable, we can take a break at any point, okay?"

Fyodor nodded, getting in to position and Dazai started drawing.

"I've never really done a portrait before, I found abstract art is more cathartic, but I don't know something spoke to me today, so a portrait it is."

"I'm sure it will be beautiful"

"Of course it will, with a subject like you." Dazai murmured, too quiet for Fyodor to hear.

A few hours later and Dazai was finished, and let Fyodor take his first look at the artwork. Fyodor had never seen himself look so beautiful, if it had been anyone else in the picture he would have said it was painted by love (but Fyodor knew he and Dazai would never get there, they may be mates, but love didn't have to feature)

"You are very talented Dazai, this picture is beautiful" Fyodor smiled, as Dazai blushed at the compliment.

"Thank you, when it has dried it's yours to do as you wish with."

"Thank you, are you feeling better now?"

"A bit," Dazai paused, "I thought I wanted to be alone today but thank you for coming back."

"No problem, do you still want to keep trying for a baby?"

"Yeah, it's only been one heat, and it was nice to spend it with someone" Dazai smiled, and pulled Fyodor in for a kiss.

Six weeks later, after another heat spent together, Fyodor and Dazai once again had an appointment with Yosano. Fyodor was waiting in the room with Yosano when Dazai finally turned up,

"I'm sorry I'm late, I lost track of time."

"It's fine, you're here now," Fyodor smiled and greeted Dazai with a kiss, Dazai sat next to Fyodor and took his hand, anxious to hear the results.

"I'm sorry, it was negative."

"There's always next month Dazai," Fyodor tried to sound positive, as Dazai just sat there, silent, "We knew the chance of success was low."

"I do wish I could offer something for you two to try to improve your chances, but there really isn't a lot research into these types of problems within Alpha/Omega couples."

"It's fine Yosano, it really is." Dazai's phone went off, "I have to go, a meeting got scheduled last minute," he turned to Fyodor, "I don't know how long it will run so I'll probably see you tonight" he placed a light kiss on his partners cheek before leaving.

"Has he told you anything about his past?" Yosano asked Fyodor,

"Not yet, I know there's a story there, but I think he'll open up quicker if I don't pry, it's not like his closest is the only one with skeletons in"

"Today could be a bad day for him, don't poke him as to why, but maybe check up on him throughout the day. I know he approved you buying a phone, so even if it's just a quick text, a funny picture, anything. Let him know you're there."

"Thanks for the advice, I'll keep it in mind." Fyodor left, making his way to the garden. Dazai had quickly noticed how much Fyodor enjoyed gardening and had employed him to work there. Dazai covered most of Fyodor's expenses, but the job in the garden had allowed Fyodor some pocket money, to treat himself without feeling like he was spending Dazai's money. He had a large pot of money left over from his grand plan, but it had been frozen when he was arrested, he knew Dazai was working on getting access but it was a slow process.

As Fyodor worked, Dazai spiralled. His meeting was done in half an hour, he returned to his office, completed his paperwork and then he was left to his thoughts. Today was a bad day for him, it was the anniversary of Oda's death, the great losses of The Guild Conflict, and the day of his two greatest breakdowns. Then to be told that once again, he hadn't succeeded in conceiving a child, was too much for one day.

He had tried to take control of the day by visiting the graveyard. He had started the tradition when he had returned from the rehab centre, and he always went alone. He spent a few hours there placing a flower on the grave of every Mafia member who had been lost since he had become boss. As well as taking time to visit Oda, he would talk about his year as he tidied the grave and placed a bouquet on his grave.

He had gone early today; he had been hopeful that he was pregnant and hadn't wanted to bring the day down by dragging Fyodor to the graveyard for his ritual. Instead it had placed a bittersweet feeling over the day, which had turned into a frustrated sadness when it turned out he wasn't pregnant.

Dazai paced around his office, nothing was working, he had tried reading, drawing, actually doing his expenses report but nothing was working. He moved to the drink's cabinet in the corner of his office, he took most of his meetings in his office, and liked being a courteous host. It was mainly stocked with hot and soft drinks, but at the back Dazai knew there was a bottle of wine, a gift from a new client he hadn't got around to giving away.

He knew he could silence the swirl of emotions if he just opened the bottle and took a sip, or he could smash it into his skin and float away. He grabbed the bottle and sat on the floor, tears dripping down his face.

Do it.

No.

Go on, do it!

You've worked so hard.

You know a quick drink will help….

As he fumbled for his phone, Dazai dropped the bottle, it smashed as it landed. Dazai paid no notice to it. Chuuya he needed Chuuya, only he would be able to pull Dazai out from himself, tell him that it was all okay. He dialled the number from memory, he kept no contacts in his phone in case it was lost or stolen, he didn't bother to check it before he pressed dial.

"I need help." Dazai's voice was the voice of a broken man.

"Dazai?"

"Fedya?"

The line went dead.

Fyodor made it to Dazai's office in less than five minutes, Chuuya was supposed to be on guard today, but was nowhere to be seen, Fyodor assumed he was in the bathroom. Dazai didn't really need a guard at the moment as everything was quiet, but as it was quiet, Chuuya had nothing else to do. Fyodor pushed the door open, not bothering to close it behind him and ran straight to Dazai.

He was still sat on the floor, his trousers wet from the pool of wine, he was staring at the shards of glass as if they held the answers to life itself.

"Dazai?" Fyodor crouched on the floor, "Can I touch you?"

Dazai nodded, so Fyodor took his hand,

"Are you alright?"

"No." Dazai sniffled

"Do you want to talk about it?"

"No."

"Okay then, how about we clean up this mess, go and have a shower. Do you want to go into my flat to paint then?"

"No, it's too bad, that won't work."

"Then we'll just focus on getting this cleaned up and you cleaned up."

"No. Too much thinking."

"I'll clean up the mess here, you focus on him" Chuuya's voice came from the door, he had just returned.

"Thanks Chuuya," Fyodor smiled. "Up we get Dazai."

"If I go with you will you make me talk? I don't want to talk about today."

"If you come with me, all you have to do is walk to your flat. No talking, no thinking. How does that sound?"

"Nice."

Dazai slowly got up, gripping Fyodor's hand, he let himself be led out of the room and back to his flat. Fyodor took them straight to the bathroom.

"Bath or Shower?"

"Shower."

Fyodor started taking Dazai's clothes off, Dazai tensed when Fyodor started on the bandages, but reminded himself the man had already seen what was underneath.

"I can't do this again Fedya. This waiting and anticipating, for nothing."

"We don't have to do a test. We can always wait until your next heat shows up or doesn't"

"That sounds even worse."

"It's an option"

"Fedya…. I want to spend my next heat alone."

"That's okay."

Fyodor finished unwrapping the bandages, and they got into the shower. Dazai stood still, the conversation having drained his energy. Fyodor washed them both, then dried Dazai's hair, and found a pair of pyjamas for them both.

"TV or bed?" Fyodor asked

"TV, but find that fluffy purple blanket. I know it's summer but I'm cold."

"Go and sit and I'll be with you in a minute."

For the next hour, they cwtched on the settee, watching a cooking competition. Fyodor was sure Dazai had fallen asleep, then, he started talking. His voice was quiet so Fyodor muted the TV.

Dazai told him the story of his past, from Oda to joining the agency, to Mori and his breakdowns and why he had spiralled today. Fyodor listened in silence, Dazai still in his arms. Fyodor reassured Dazai, told him he was so proud of him, and thanked him for sharing his past with him.

Then, Fyodor shared his past, finding out his ability when he touched his mother in anger, how he had found out about The Book, why he had worked so hard to rid the world of ability users, and why he had been okay to abandon it all when he had finally made it to Yokohama.

From that day on their relationship changed. They understood each other better, and knew how to handle each other's bad days. They still didn't spend every night together, sometimes Dazai had late meetings and didn't want to disturb Fyodor. Dazai had decided to spend his next heat alone, as it was too close to his breakdown and he wanted to be free of the lingering emotions before they tried for a baby again.

It was now mid-August, Dazai had woken up to a message from Fyodor telling him he was unwell and that he had let the head gardener know he wasn't coming in today. He followed it by asking Dazai not to check up on him, as he preferred to spend illnesses alone. Dazai wasn't happy about that, but as Fyodor respected his boundaries, Dazai would do the same. He had a meeting with Ane-san, Hirotsu and Fukuzawa and the rest of his day was free, so he would check in on Fyodor then. As he left his flat, Fyodor's scent hit him as he waited for the elevator, he knew his partner had good control over his scent so he must really have been unwell to have let go of it that much.

Dazai tried to quell the panic that Fyodor was more unwell than he had let on, and made his way to his meeting. He lasted half an hour before he started feeling strange. He was weeks away from his heat, but his temperature was rising, and he could only thing of Fyodor.

"Dazai? Earth to Dazai." Ane-sans voice sounded like it was miles away.

"Ye—yes?" Dazai struggled to speak, he shook his head trying to move the fog,

"Have you heard anything I just said?" she asked

Dazai thought, all he could thing of was making himself nice for Fyodor,

"Honestly? No, Fyodors unwell, and his scent was really strong when I went past his flat this morning and now my thinking is all fuzzy."

"Does you omega want to make you all pretty for your alpha?" Fukuzawa asked.

Dazai nodded, glad at least one person in the room could understand what was happening to him.

"Go, we can finish this meeting without you." Fukuzawa told him, the other two nodding in agreement,

"We'll cover your schedule for the next week, so don't feel obligated to come back before Fyodor's feeling better," Hirotsu added

"Thank you." Dazai smiled and left his office.

Fyodor's scent was still strong when he returned to their floor, he wanted to go straight to him, but his omega was adamant he needed to shower, shine up his hair and present himself all prettily for his alpha. He showered quickly, he was sweating within minutes of getting out, his higher temperature had given way to his heat. He moved to his bed, not wanting to get slick on the floor, he didn't want to disturb Fyodor when he was ill, so he reached into his drawer for a toy.

There was growl at the door, Fyodor had appeared without Dazai noticing, he had a wild look in his eyes. He was wearing only a pair of boxers, it did nothing to hide his erection. Neither of them realised it, but Fyodor had gone into rut.

"Drop. It."

"Fedya? I thought you were ill?"

"You smell so damn good my love." Fyodor shut the door behind him and quickly made his way to the bed. Dazai spread his legs, presenting himself to his Alpha, Fyodor kissed him.

"So pretty, you're such a good omega for me, aren't you?"

"Please Fedya"

"Hmm you asked so nicely, maybe we can begin."

It had been so long since Fyodor had gone into a rut, that it was three and a half days later, when they finally came back to reality.

"How are you feeling my love?" Fyodor asked as Dazai slowly tried to sit up, they had collapsed and spent half an hour cwtching as they slowly cooled down and returned to reality.

"My ass aches, my neck aches, actually all of me aches, and I'm sticky." Dazai grumbled, although he was smiling.

"Mmm I'm sorry, I got a bit carried away." Fyodor placed a light kiss on Dazai's lips.

"It's fine, it was nice to see that side of you." Dazai smiled.

"Do you want a shower or a bath?"

"Both, shower first then I want a nice relaxing bath, it should help the aches." Dazai moved from Fyodor's hold and slowly stood up, he whined as he took his first step. Fyodor came to his side and helped him into the bathroom, he turned the taps on to start filling the bath and added Dazai's favourite bubble bath. Then they got into the shower, it took fifteen minutes, but Fyodor was finally content they were both clean enough, he wrapped a towel around himself, then helped Dazai into the bath, he sighed in bliss as the warm water soothed his aches. Fyodor kissed his forehead

"I'm just going to grab some things, I'll be back shortly."

"You'll come back though?"

"I'll leave the door open and I'll just be a shout away, okay?"

"Good"

Fyodor returned five minutes later and slipped into the bath with Dazai,

"A few more minutes and then we'll get out okay?"

"Mmm it's nice in here though,"

"We're not sleeping in a bath,"

"Spoilsport." Dazai pouted, then yawned.

"Times up, lets get you dried and dressed before you fall asleep on me."

They got out of the bath and Fyodor plaited Dazai's hair. It was summer so it would dry quick but he wanted Dazai to be comfortable in his sleep.

Whilst Dazai had relaxed in the bath, Fyodor had stripped the bedding, set out a pair of pyjamas for Dazai and made porridge. Dazai put the pyjamas on and started eating the porridge, as he did this Fyodor made the bed and joined Dazai with his own bowl of porridge.

"Thank you Fedya,"

"No problem, I checked our phones, we've been out for three and half days."

"Really?! No wonder I feel so worn out. Were there any messages?"

"Just one off Ane-san reminding you they had given you the week off and to let them know when you were reachable again."

"Hmm I think we can sleep and then I'll message her."

They finished their porridge, placed the bowls in the dishwasher, cleaned their teeth and settled into bed. Fyodor cwtching Dazai

"Why did you decide to bond with me Fedya?"

"It seemed right, my knot swelled and my alpha was just screaming to bite you. I'm sorry I should've asked first."

"I… I don't mind that you did it, I know I encouraged you, and I don't know it feels….right?"

"Yes it does." Fyodor couldn't help smiling, feeling proud he had an omega to call his own.

Content they fell asleep cwtched in each other's arms.
