what I'm getting from this is, Dazai is into Chuuya in all of them, Chuuya is chill with it infact like him back a bit, but would never admit that shit. Fyodor would S/A someone and Kunikidas down bad.
With the ending, I now need a fanfic of BEAST AU, where they react to dazai and the universe thing alongside his life, sort of like 'Leafing Through The Pages, I Found You' but BEAST AU, and then in the end for Oda and Dazai to be friends, and the rest to somehow forget memories to keep the balance (dazai and oda know)
