@Alexnightmoon personally something with Overhaul(from bnha) would be interesting couse he a germaphobe and doesnt like poeple with quirks, so something like a soul mate AU. Maybe he doesn't except he found his soul mate at first but the keep trying. Or you could do something like, Eri gets separated from him in public and someone suggesta that Eri needs a baby sitter and he agrees to let them baby sit them and he slowly takes an interest with them. Just an idea, can wait to see whatever you do.
