Midoriya had wanted to propose to y/n, but he had been too shy. Therefore, he’d asked y/n’s brother, Shoto Todoroki, to do it for him.

(Todoroki) Hey, uh, y/n? Midoriya wanted to know…he pulled out an engagement ring if you wanted to marry him..? He was uncomfortable, but Midoriya was his friend, so he was doing it

(Bakugo) mumbles yeah, because the damn nerd was too nervous to ask himself..
