Mr. Aizawa decided that in order to help his students progress, he’d call in a secret pro hero to help them train. He divides his class into groups of three, each going to go up against the individual hero. The problem—this pro hero is nearly impossible to beat. Y/n’s quirk is unlike any other and even just getting near them is the most difficult struggle. Oh—and another thing—Aizawa and Y/n have a…history. They dated all throughout highschool. But when they graduated and hero work consumed both of them, they quickly realize a relationship just didn’t fit in with their schedules and mutually agreed it would be best to separate. However, they both still clearly had feelings for each other and as Aizawa watches each of his students go up against them— He starts remembering why he fell in love in the first place.
