Read the fucking title it's pretty self explanatory (No smut)

Hawks has never wanted anyone or anything as much as he wanted Dabi, so in the dead of night, with a drink and a pill, he snatches him from under the league. With the winged hero refusing to ever give him his freedom back, Dabi's gotta try to figure out how to get through the days and escape before too late...but Hawks is a bit more clever and dangerous than he originally thought. Hawks is determined he will win him over, mind break or not. Once he sets his sights on something, he never loses his target. And he WILL NOT lose his Dabi.

Shigaraki has learned and found out EVERYTHING about Dabi that the fire user was desperately trying to hide from. His past, his pain, his abuse, his father, his name, his weaknesses and even worse...his fears. He sure isn't happy about the dishonesty and withholding of information, but he definitely has quite a bit to work with. They've been dancing a line that Shigaraki is determined to cross, even violently if necessary. What Shigaraki wants, he gets, and he wants Dabi until the end of time. Even after.
