You’ve been dating Denki for a while, so every time he short circuited, you’d take care of him until he’d recover. Though, he’d always feel bad that you had to take time out of your day for his stupid antics.

So, without telling you, he’d train with his quirk any time he could to resist short circuiting.

Class 1-A was on a mission. Denki used his quirk and you thought he was going to short circuit. You went to find him until some debris almost crushed you.. until Denki saves you?!
