    Three Months Later
  
 
  “Dazai-san, it’s not a big deal. Can you please just focus on your work?” Atsushi sighed, trying his best to finish the report before lunch.

  "Chuuya is a horrible influence on you. You used to be so easy to bully," The man in question whined, before going off to pester someone else (most probably Kunikida, considering that the others were out doing errands).

  It was a Saturday morning, but they were called into work due to 
  
    unforeseen circumstances 
  
  which probably meant that it had something to do with Fyodor, Dazai and somehow, the whole of Yokohama.

  Atsushi spent the first half of his very early morning investigating leads and the next half typing up reports of his not-as-successful-as-he-liked investigations. For something that was deemed an emergency, it sure was shaping up to be a slow day.

  Honestly, he would be fine with it, if it wasn’t for the fact that he was supposed to go out with Ryuunosuke that day.

  They were going to go to the theme park so he had dressed down for the occasion. He was decked in the ripped skinny jeans Kyouka had gotten him for his birthday and a yellow, oversized hoodie which Ryuunosuke seemed to be fond of for some reason. He was also wearing his best sneakers (which cost him half his salary), looking every bit like a college student with time to spare, so it was understandable when people questioned his credibility.

  Just because he understood their reservations and reluctance to cooperate, it didn’t mean that he wasn’t annoyed at the whole situation.

  His patience was already tested (he had to skip out on the breakfast Ryuunosuke had prepared for them) and now that Dazai’s pestering him over his date with the other, he was 
  
    this 
  
  close to-

  “Atsushi, someone's coming!” Naomi said from her desk, putting down the phone and looking at him knowingly.

  Atsushi stopped planning Dazai’s murder in favor of thinking things through.

  (It was weird for a client to call ahead of their arrival. Usually, they would just knock on the door and enter the Agency. It didn’t matter if they had an appointment or not. They usually accepted walk-ins.)

  Brushing it off, Atsushi stopped drafting up his report in favor of welcoming whoever it was that needed help on a lovely (debatable) Saturday morning.

  He turned his attention towards the door, internally crying at the thought of drafting yet another report but stopped short when he saw the person who decided to show up.

  “Are you ready to go?” Ryuunosuke asked, uncaring of all the stares he was subjected to.

  Atsushi could kind of understand his co-workers’ feelings, though. It was the first time, in their three months of dating, that Ryuunosuke willingly set foot in the Agency.

  Not only was he 
  
    there
  
  , he was also dressed differently. Usually, the man would be in his Port Mafia uniform or in his home wear (understandable, considering that they were now living together). When they went on dates, they would usually dress formally since the restaurants his boyfriend took him to were 
  
    fancy 
  
  fancy.

  Now that he thought of it, this was his first time seeing the mafioso dressed this way. He was wearing a black leather jacket on top of a black Pink Floyd tank top, tucked into black, skinny ripped jeans. He donned a pair of black Vans and… were those… 
  
    silver cross earrings?
  

  Atsushi felt like he was going to pass out.

  “If you aren’t, it’s fine. We can always go somewhere else and visit the amusement park on another day,” Ryuunosuke said, mistaking his shocked silence for guilt over not finishing his work.

  Under normal circumstances, he would be right but now? Now, he was busy trying to kickstart his brain because he could not, for the life of him, produce a single coherent thought.

  “Wait… is that… 
  
    Akutagawa
  
  ?” Tanizaki asked as he entered the room, two coffees in hand.

  He passed one to Naomi and took a sip from the other, casually approaching the man who had almost killed him a while back. 
  When he confirmed that it was indeed Ryuunosuke, he let out a low whistle and turned to look at Atsushi, who was still trying to process things.

  “I’ll finish up your report. Why don’t you go on that date now?” He suggested, walking towards the weretiger’s desk and forcefully pulling him off his chair and pushing him towards the mafioso's general direction.

  Ryuunosuke chuckled at the display, shaking his head fondly. He then used Rashomon to curl around Atsushi’s wrist before tugging him gently.

  Atsushi finally snapped out of his stupor, blushing a deep red. He let himself be dragged along, not even turning to glare at Dazai’s teases. Once they were outside, Atsushi turned to look at his boyfriend who looked way too smug.

  “Like what you see?” He asked smugly, knowing full well what the answer was.

  Atsushi groaned, covering his face in embarrassment. 

  “Shut up.”

  The mafioso laughed, before using his hands to pry Atsushi’s off of his face. Feeling defeated, he reluctantly uncovered his face and dropped his hands down. Ryuunosuke then took the opportunity to hold them, interlacing their fingers together.

  “Should we go see the cherry blossoms instead? I heard that they’re in bloom around this time. We can go eat lunch first at that noodle house you love,” The mafioso suggested as they made their way to his car.

  Atsushi hummed, contemplating his choices.

  On one hand, he really wanted to go to the theme park but… it was already noon. They’d already missed out on half the day and he’d have to leave early in case anything happened at work. He wouldn’t be able to enjoy it fully with Ryuunosuke and he didn’t want their first time together there to be marred.

  Cherry blossom viewing, on the other hand, was also something that he’d wanted to do ever since he was little. Sure, it wasn’t what they originally planned but any time spent with the mafioso was time that he cherished.

  “Sounds good! I’m paying this time, though.”
At Ryuunosuke’s displeased expression, Atsushi laughed aloud, amused at his annoyance. For some reason, he was hellbent on paying for all of their meals together. Atsushi knew that the Port Mafia paid a hefty amount, especially for someone at Ryuunosuke’s level, but d@mn the man was generous.
  Soon enough, the mafioso joined in on his laughter, physically unable to stay grumpy when Atsushi was smiling so brightly. 

  They reached Ryuunosuke’s car in no time and before long, they started their journey. 

  Atsushi was crafting their road trip playlist on Ryuunosuke’s phone, playing songs to fill in the silence. It was a recent habit they picked up after returning to their universe.

  One thing they learned from their time there was that it was never too late to experience things they didn’t get to when they were growing up. It didn’t make them childish or immature, now that they were doing it as adults. It simply meant they were, well, doing things. 

  Because of their childhood, they didn’t really have much time to explore different artists but now that they had more freedom, they took the opportunity to discover more. They even recommended to each other artists that they think the other might like. 

  (Dazai had teasingly called them lovestruck teenagers in those cheesy rom coms but neither of them minded. Besides, Chuuya dragged him out to work on a case despite it not being Dazai’s because of that. It felt like a win.)

  It was also kind of ironic, in a way, this habit of getting to know these artists, taking into account the fact that people well into the future (and in a whole different universe!) such as Kaminari and Kirishima deemed them 
  
    legends with classic bangers. 
  
  He remembered them being appalled that he didn’t know who The Beatles were.

  (In his defense, he was Japanese and he lived in Japan. Not only that, but the orphanage restricted him from using the Internet. It’s not like the radio stations he used to sneakily listen to played Western songs! Much less songs from the 50s!)

  He was reminded of a particular memory.
 
  
    “But it’s 
    The Beatles!” 
    Kirishima said, scandalised.
  

  
    “Next thing we know, you’re going to say you’ve never heard of Rick Astley!” Ashido exclaimed, putting a hand her chest and clutching it in mock pain.
  

  
    Kaminari caught her as she pretended to stumble, looking equally horrified.
  

  
    “You’ve… heard of him… Right?” Sero asked tentatively.
  

  
    At Atsushi’s apologetic smile and Ryuunosuke’s raised eyebrow, they gasped dramatically before pulling the both of them towards the nearest computer. They spent the next few hours going through YouTube, though they sidetracked from the main goal and ended up watching cat videos instead.
  
 
  At the thought of them, Atsushi smiled sadly.

  It had been months since they departed the universe, with no way of contacting them. They had even gone to visit the criminal they were after to ask if there was any way they could communicate with the other universe.

  The man didn’t really want to comply but after several threats from Ryuunosuke, the man admitted that he didn’t know for certain. As he mentioned before, not many people made it out of his Ability alive and the people who did weren’t really on good terms with him. 

  But… he didn’t outrightly say it was impossible. That meant that there was still hope. Even Ranpo hinted towards the possibility, encouraging them to continue on with their investigations. He would’ve straight up told them otherwise if it wasn’t feasible.

  “How do you think the others are doing?” Atsushi asked as he hit play on one of the songs they listened to on that day and turned to look at the mafioso.

  The first few notes of The Beatles’ Yesterday played in the background as Ryuunosuke contemplated his answer.

  “Izuku and Shouto are definitely getting into all sorts of trouble. They might even rope Uraraka and Iida along. Touya-san is probably encouraging them and Aizawa sensei might be contemplating early retirement. Just the usual,” He said humorously, switching on the indicator and glancing at the side mirror before changing lanes.

  Atsushi laughed, nodding in agreement.

  “You’re right. Oh! And they might’ve executed that Endeavor plan we came up with before amp.”

  Ryuunosuke smiled at that, though it wasn’t particularly friendly. In fact, it looked a little bit 
  
    too 
  
  sinister. But… it was Endeavor, after all. Whatever he got, he probably deserved it.

  “Ah, it would’ve been such a sight. It’s a pity we left early. If only we could stay for just a little bit longer,” The mafioso lamented, eyes drifting towards Atsushi for a split second and noticing his sad expression before looking back at the road.

  He cleared his throat, blushing as he said his next words.

  “We’ll find a way, love. Don’t worry.”

  (Ryuunosuke’s new habit of calling him by various endearments will be the death of him.)

  Atsushi blushed heavily, shyly thanking him for his words of comfort. He then scrolled through Spotify, still feeling a bit flustered and desperate for something to do. 

  In his haste, he accidentally pressed the library icon, eyes immediately drawn towards the playlist at the very top, titled “him”. Feeling a bit curious, he pressed it. 

  He scrolled down the list of unfamiliar songs, before deciding to play a random one.
 
  
    Even if my heart stops beating,
  

  
    You’re the only thing I need, ooh, with me.
  
 
  “I didn’t know you listen to The Neighbourhood,” Ryuunosuke commented, tapping his fingers in time with the music.

  “I don’t. I found this in your playlist,” He answered absentmindedly as he looked up the lyrics. 

  He could hear the tapping stop. Confused, Atsushi turned to look towards Ryuunosuke who was blushing a deep red.

  He wasn’t quite sure why the other reacted that way. It was his own playlist. 

  (He couldn't possibly be embarrassed by his own music taste, right? 
  Judging by the way he was nodding his head along, that didn’t seem to be the case. So why else would he be embarrassed?)

  Atsushi looked through the playlist as if it was going to give him answers. 

  He went through the songs again and scrolled all the way to the top, before noticing the title and the description.
 
  
    him
  

  
    my one and only
  
 
  (
  
    Oh.)
  

  Atsushi exhaled shakily, feeling a rush of emotions as he processed the implications.

  Ryuunosuke created a playlist for him, and judging by the song titles, they were about 
  
    love
  
  . He listened to those songs and thought of 
  
    him. 
  

  (Though.. some of them didn't really imply happy endings? He wasn't quite sure.)

  “I… didn’t expect you to ever find out,” He said after a while, voice softer than Atsushi’s ever heard.

  The weretiger turned to look at him, noticing the way the other was gripping the steering wheel tightly and frowning slightly. He looked anxious.
“Some of the songs aren't... well, you've seen them. They aren't particularly optimistic but it's not because of you, or because I'm unhappy. It's just..." He exhaled slowly. "I’ve had it since the day we broke that promise to duel each other to death after six months.”Atsushi almost dropped the other's phone in shock.
  That was… a long time ago. Way before they even set foot into the other universe. Could that mean…?

  “I’ve had feelings for you for a long time now, Atsushi.”

  Atsushi groaned in embarrassment, his heart pounding rapidly as he brought his hands up to cover his red face.

  He couldn’t understand how Ryuunosuke could just…. say those things without wanting to explode. He was already close to having a heart attack listening to them.

  “How are you so perfect?” Atsushi whined from behind his hands.

  Ryuunosuke chuckled at that.

  “I’m really not, but thank you.”

  They listened to the playlist together for the rest of the drive, Atsushi’s heart going into overdrive as he listened intently to the lyrics.

  Sometimes, Ryuunosuke would softly sing along under his breath and he would listen to him instead, not processing the words but marveling at the beauty of his voice. 
(It was really nice.He still couldn't quite believe that he had the privilege to witness this side of the man.It felt like a fever dream.)
  Before long, they finally reached their go-to noodle house whenever they needed a pick-me-up.

  Atsushi wordlessly passed the phone back to Ryuunosuke as soon as he pulled the brakes and killed the engine, blushing slightly as he did so. 

  (Even after multiple car rides together, he couldn't quite get over the fact that the man looked attractive while driving. It was ridiculous.)

  As he hastily exited the car, wary of the man's growing smirk, his forced his thoughts back to that particular noodle house, and the meaning behind it.

  Right after their return to this universe, they went out to eat after apprehending the criminal and completing all the on-site paperwork needed. Since they had a long-standing 
  tradition of going to a noodle house after every bad event that took place in the other universe, they decided that there was
   no harm in continuing it and did just that.

  A few more missions which ended up with them frequenting this particular noodle house, Ryuunosuke had said something about the benefits of maintaining some sort of routine from Izuku's universe to better cope with their homesickness and promptly asked him to move in with him.

  It was a pleasant surprise, though he had a nagging feeling that the man had eluded to the topic before, even when they were in that other universe.

  Shaking his head fondly as he recalled their previous memories, Atsushi iwent over to Ryuunosuke's side and intertwined their fingers before dragging him towards their usual table, grinning at their usual server when she waved at them.

  Lunch was a pleasant ordeal, save for the multiple text messages Atsushi received throughout the whole meal. He decided to ignore it for the time being, deciding that if it was 
  
    truly 
  
  important they would’ve called him instead.

  But Fate (or well, Dazai) had other plans.
 
  Dazai-san

  atsushi pls omg u womt believe thsi

  omg atsushi dont ghost me

  its nit a prank i swear its important

  ok jk it was a prank d@mn u’re smart
 Atsushi sighed, about to put his phone on silent when it vibrated viciously the next few seconds. 
  Dazai-san

  ATSUSHI OMG!!!

  OMG PLS

  ITS LEGIT THIS TIME

  *NOT CLICKBAIT!!!!*

  no but srsly 

  atsushi plz
 
  He groaned as his phone dinged for the umpteenth time, looking at Ryuunosuke apologetically. The mafioso smiled understandingly so he proceeded to call Dazai.

  “This better be important, Dazai-san.”

  He could hear raised voices in the background and… was that Kyouka-chan threatening to disembowel a stranger?

  (Huh, seems like most of the Agency members were done with their errands.)

  “Atsushi-kun, you wound me! I would 
  
    never 
  
  joke about things this serious!”

  He rolled his eyes at that, remembering the hundreds of times he fell for jokes of that exact nature. Nevertheless, he decided to humor the man so that he could continue with his date.

  They still had cherry blossoms to view, after all.

  “Alright, Dazai-san. What’s the matter?”

  It sounded as if the man was walking towards the commotion, judging by the increase in volume. Kunikida was heard interrogating someone while Naomi squealed in the background for some reason.

  It wasn’t really making any sense.

  Atsushi frowned at Dazai’s silence, shaking his head and shrugging his shoulders when Ryuunosuke asked him what was going on.

  He had half a mind to just… hang up the phone and deal with the consequences later. He could see the mafioso inconspicuously eying the bill, wanting to pay for the meal despite Atsushi’s previous offer to cover it.

  Before he could do so, however, a familiar sounding voice stopped him in his tracks.

  “Atsushi-kun, you really weren’t kidding when you said you were in your 20s - wait, should I call you Atsushi-san instead? What year were you born in, punk?”

  Atsushi turned to look at Ryuunosuke, eyes wide as he tried to comprehend the situation. The mafioso looked at him worriedly, but said nothing.

  “Touya-san?”

  Ryuunosuke’s eyes widened.

  “Atsushi, do you know him?” Kunikida asked, still on guard.

  Atsushi nodded his head before realising that they couldn’t see him. He cleared his throat before answering.

  “It sounds like someone I know but I’ll need to see him first to confirm his identity.”

  At that, they switched to video call so that Atsushi could identify him.

  Apparently, Touya(?) randomly appeared inside the Agency without any of them noticing. The CCTVs didn’t capture any movement in or out. It was as if he just materialised out of nowhere.

  Atsushi went over to Ryuunosuke’s side so that he could see what was going on as well, both of them holding their breaths as they waited for Dazai to show the man.

  The sight that greeted them made them figuratively scratch their heads in confusion.

  He 
  
    looked 
  
  like Touya but there were some noticeable differences. One of them was that he had now had white hair instead of black, but the most obvious change was the lack of scars that used to mar his skin. In fact, he had absolutely none.

  “What…?” Atsushi began, feeling too shocked to even continue his sentence.

  Touya laughed at his reaction before shaking his head.

  “Long story short, the regenerative quirk All For One gave me 
  
    didn’t 
  
  turn me into a Noumu but fixed up every single f@ck up.”

  That… sounded plausible. Convincing even. Not many people would know about All For One and what transpired that day. But… he couldn’t be too sure.

  Fortunately, Ryuunosuke felt the same.

  “Really, now? What was the first thing you said when you saw me?” He asked, narrowing his eyes in suspicion.

  Touya smirked at that, feeling confident.

  “I asked Atsushi if he was two-timing Shouto with you. Oh, speaking of that, are you guys finally dating or…?”

  (Yup, that was definitely Touya.)

  They laughed at that, feeling relieved and nodding their heads in unison.

  “Thank f@ck. I have to tell Aizawa this. Poor man needs to hear some good news after everything.”

  Everything could mean anything ranging from the usual trouble 1-A would give him to Izuku levels of trouble.

  (Atsushi had a feeling it was the latter and that it was bad. He was happy to see Touya again, well and healthy but
  ... what was going on? Why was he here in their universe? Where were the others? What happened in the short three months since they've left?)

  “Don’t really want to interrupt your reunion here but we do need a confirmation on his identity,” Dazai interjected, sounding serious (for once).

  Sobering up at that, Atsushi immediately gave the green light and was immediately told to come to the Agency so that they could figure out what was currently happening.

  “I think it might have something to do with Fyodor, that pesky little sh@t,” Dazai grumbled, ending the call soon after.

  Atsushi turned to look at Ryuunosuke apologetically.

  “I’m sorry we can’t go see the cherry blossoms,” He said.

  Ryuunosuke smiled warmly, shaking his head.

  “It’s fine. Work is work. Besides, we’ll be meeting Touya-san again.”

  Atsushi looked at him fondly, feeling infinitely grateful that he had such an understanding and accommodating boyfriend.

  “Have I told you that I 
  
    really
  
   like you? Because I do. So so much,” Atsushi said as he leaned in to kiss him on the lips.

  Ryuunosuke hummed, kissing him back briefly before pulling away, not wanting to cause a scene in public.

  “I really like you too.”

  With that, Ryuunosuke paid the bill (that traitor!) and they left for the Agency.

  Touya’s appearance in their universe, coupled with Fyodor’s possible interference could mean a potentially catastrophic disaster in the future but for them, that didn’t matter as much.

  Funnily enough, what mattered more was the fact that their universes 
  
    could 
  
  collide and that they could possibly meet up with the others again in the future. That their separation wasn’t a 
  
    goodbye 
  
  but a 
  
    see you later.
  

  They'll figure out the technicalities later, work together with the others (the Agency and Port Mafia this time) to come up with a plan to stop the impending doom coming their way. 

  The last time they were in trouble, Izuku's universe and it's occupants had generously helped them get through it and now, it was their turn to repay the favor.

  When Atsushi and Ryuunosuke first stepped into that world, they didn’t expect to be attached or to form bonds that could last a lifetime. 

  They faced a lot of trials and tribulations, made a few friends - hell, even 
  
    family
  
   - and righted a few wrongs. They were also able to heal and grow, finding themselves and finding each other. It was an extraordinary experience and they were grateful for whatever miracle it took for them to cross paths.

  Life was never kind to them for the longest time but now, it felt as if things were about to change for the better.
