DESPERATELY trying to find a fic

The fic was BSD. It started out a with Fyodor x Dazai, but like in a bad toxic Stockholm syndrome kinda way, I don't remember much of it, just that eventually Dazai became very dependent on him, and then eventually the ADA and chuuya found and rescued him, but Dazai was not okay with that, cuz like, dude was traumatized. I can NOT remember what it was called for the life of me but I need to find it again bc it was so good. If I remember anymore details I'll add them!!!
