It's been some years already since Dazai left the Mafia, he was like your best friend before, until he left.

Today there's a meeting between the Port Mafia and the ADA, you were excited at first because you could see Dazai once again, you were hoping he would recognize you at least.

“Who are you?”

That's the answer you got from him.. not even a friendly Hi or something like that, just a simple answer that at the same time hurt you a bit, how could he not remember you?
