Dazai has been working in the port mafia since he was 15, now he is 18, brown hair, brown eyes, wears bandages, tall, 180, somewhere cold, serious, well, and so he is sometimes like this more often, he drives everyone crazy, he has many masks and roles, he is real only with Chuya, his best friend since childhood and he did not want to tell Chuya that he was going to the mafia, and Chuya did not want to tell him, in the end, on the very first day, they saw each other there and realized that Dazai worked in the same place, well now they could not hide it, Dazai often plays tricks on Chuya and gets slaps on the back of the head for it, but they both got used to it, most often Dazai calls Chuya "chibi", at first it was like a joke, but now it’s just boring and sometimes "baby", at first it was also like a joke and now it’s also boring, but he tries to call him that way, for example, when they are at home, yes, they live together, because it’s more convenient, well, in short, so that no one hears, otherwise They'll think Chuya is already normal
Chuya has been in the mafia since he was 15 and he's also 18, he's two months older than Dazai, his red hair is just below his shoulders, but in a ponytail it creates the illusion that it's short, Dazai sometimes begs to cuddle it, his blue eyes are very beautiful, he always wears his choker and gloves, he's low, somewhere around 160, he's always irritated, but with Dazai he's kind and calm, not always, shorter, his friends are great, he also sometimes teases Dazai, but very rarely calls him "bandaged", "chestnut", but more often by his first name, he lives with Dazai and he's fine with it, sometimes they get mad, sometimes when it's sad, someone comes to hug him, or during a thunderstorm, Chuya comes to Dazai, because he himself can't sleep, it seems, that's all
STORY
One day, Dazai and Oda were sent on a mission, but Oda died. Dazai tried to save him, but nothing happened. Oda only said before he died, "Don't lose Chuya, just like you didn't lose me." Knowing that they were best friends, Dazai was walking back, barely holding back his tears. Suddenly, at the Mafia's door, Chuya ran up to him and, without noticing, said, "Oh, Dazai! You've been taking so long, and where's Oda?" Then he noticed his clenched fists and tear-filled eyes, and he realized that Oda was dead, but Dazai couldn't hold back his tears.
