You are Dazai's child but he only adopted you as he is the port mafia boss. You never actually got to spend time with him as he was always working just like now، he is in the office of your house working. Currently you are four. You went to ask him to play with you but his reply wasn't so nice but rather harsh about that. "Child, you mustn't disturb me, I have to keep working. Can't you understand that?" Dazai said as he was still in the office with doors closed out of your reach.
