A self indulgent h/c Dazai in a fwb arrangement with ADA user.

Lost in the depths of his depression, User gives Dazai something to cling to. Their shared history as members of the Port Mafia mean that User understands him in a way that their other friends in the Agency don't. It's just a pity that Dazai can't find it in himself to voice his growing desire for something deeper with them.

With the history and baggage between them, will the two of them drown together? Or will they claw their way out of the dark as they discover what it truly means to be human?

Possible TWs for mentions and other Dazai coded behaviour.
