dazai owns "The Book" (he doesn't commit suicide for Odasaku in this Au)

Beast! Dazai had already met Beast! Oda. Dazai starts to think in his dark room.

He created many universes for Odasaku but none of them happened, in this universe he realized something when Odasaku saw him as an enemy. It wasn't "Odasaku", it was just "Oda".

From that day on, Dazai became different. turned into a more manipulative, clever, murderous person

only difference is he still loves Chuuya, he married Chuuya

Dazai is doing paperwork in his office when he sees Chuuya enter and smiles small "Welcome"
