Odasaku's Last Wish (Dazai X Male!Reader)

I

"Dazai!" The man opened his eyes to see kunikida staring at him, angry as ever. "Yes?" Dazai said in a sing-sang voice, irritading the other more. "You're supposed to be correcting you're last report! My ideals say, you should have been done fifteen minutes ago!"
Oh, yeah his ideals. Even though dazai would never admit, he loved those ideals. They reminded him of him. They reminded him of what had been his dying wish. The only thing he regretted about it, was that he would never be able to see (Y/n) again. "Oh, calm down kunikida. I made atsushi correct them for me." He waved his hand dismisively, and continued listening to music. Kunikida only grew more irritated, with a look of disbelieve. "You made atsushi do them?!" Kunikida barked at him, about to hit him over the head, when fukuzawa stepped in the room, giving all of them a pile of new cases. "The police said these are the newest batch of unsolved cases. I believe you can help them out." Dazai sat up, and went to the cases immediately. "How can you go to a new case!? You're not even done with you're report that you made atsushi do!" Kunikida heard someone clearing their throat, and turned to see atsushi with an apologetic look. "I kinda just finished them." He said scratching the back of his neck. Kunikida let out a defeated sigh. "Told ya!" Dazai said tryumphantly. "Plus, working on the case is far more interesting than writing about-" Dazai paused, looking closer at one of the cases in his hands, putting the other one down. "It..." he finished his sentence, knowing kunikida and atsushi would want an explanation. "What? What is it?" Atsushi asked nervously. Dazai made an 'oh' face, and shrugged. "Oh, I just missread something, don't worry. I'm still gonna do this one though, it intrigues me." He sat down on his desk and started typing something on his computer, then stood back up and left the agency. "What the hell?" Was all kunikida could say. "What was that about?" Atsushi yelped out.
Everybody looked at ranpo, him kind of being their only hope of understanding this situation. "Give me sweets, and I might know." Was all he said. Kunikida let out an annoyed huff, grabbed his bag, and pulled out some lollypops. "You keep candy in your bag?" Atsushi asked, pointing towards it. "For situations like these, yes." Kunikida handed ranpo the candy, and waited for an answer. Ranpo unwrapped it, and stuffed it in his mouth immediately. He looked around, seeing as everyone was, again, looking at him with anticipation. "Oh, I have no clue what that was about, I just wanted candy." Everybody groaned at that, and begrudgingly went back to work.
Dazai on the other hand, was ecstatic and at the same time nervous. When was the last time he was nervous? He couldn't really remember. All he knew, was that (Y/n) was in Yokohama, and wanted the ADA to help him with a thief that the cops couldn't catch.
He went to the adress on the file, arriving in less than half an hour, he was a speedy walker already, and the hope of seeing him again, after what? Three or four years, was speeding him up even more.
Once he was standing in front of the door, he was scared. Why was he scared? Would he even recognise him? He hadn't changed that much in apearence, but his attitude sure did. He kept stalling. He feared (Y/n) recognising him more, than he did him not recognise him. He feared he would pretend to no longer remembered him, or he would hate him for what happened. He had always blamed himself for it, deep down, he knew it wasn't his fault, but he didn't want to admit that as the truth.
He took the deepest breath he could muster, but still wasn't couragous enough for the knock.
