Derek is being pressured by his family to pick a mate, and somehow stumbles into a choice that they didn't expect and aren't sure they approve of....

In one world, the members of Class 1A, for the most part, had support systems and ways to cope that let them take things in stride. In another, they are left far more vulnerable to the traumas inflicted on them over and over. It all started with Todoroki Shouto seeing bruises on Yaoyorozu Momo's arm. The members of Class 1A begin to realize they are all far more alike than they thought, and the insecurities, fears, and pain they are facing are too much to handle- and so they decide to run as far away from them as they can, because if the world won't give them family, they'll be each other's family.

“I’ll destroy a man for you,” he says breathlessly. Todoroki looks vaguely amused. “Good to know.” Midoriya passes the mug to Momo’s hands and then reaches up to put his hands on Todoroki’s cheeks so he can bring him down to eye-level. “No, listen. I will destroy a man for you.” Todoroki blinks at him, looking a little startled. “I have a seven year plan,” Midoriya elaborates terrifyingly. “O-kay?” he says throught his smushed cheeks. “Fuck Endeavor,” Midoriya says empathically. (Or: Midoriya has absolutely no filter when he's sleep deprived. That's it. That's the fic.)
