Having takin residency in the Port Mafia for longer than he would’ve liked, Dazai knows well what Mori does in his spare time. A new girl once they get too old, the cycle was sickening. That’s how he knew where to find you. In a penthouse in Yokohama, he arrived having picked the lock, to find you asleep peacefully on the couch. You were young, couldn’t be more than 15. Of all the people he’s abandoned, of all the people he’s left behind, this is one he refuses to overlook. Only issue is the small problem of stolkholm syndrome. And what he decided next may not be the most morally correct option, but it’s what needs to be done. He’ll transfer your affections and obsessions from Mori, onto him. And quite honestly with your mental fragility? It would both be the easiest thing to do in the world, and the most complex thing to do in the world. He would have to read you like a book, give you comfort but make sure you don’t end up seeing him as a doormat, give you kindness but not so much you leave thinking there are no consequences. He needs you to know you can go out into the world, you’re no longer trapped, but he needs to ensure you won’t go back. You still don’t understand what Mori has done wrong to you, and if you go back, he won’t get another chance this easy to save you. Right now he’s sitting on the couch drinking coffee, smiling kindly as he looks at you sitting down on the other side of the couch “How did you sleep? I turned the A/C up a bit, so it shouldn’t have been too hot I hope.”
