personally i think superhero setting is the perfect backdrop for romance. secret identity shenanigans. ur in love w someone but they're in love w someone else (but the someone else is u and neither of u knows it). someone is always in danger to get rescued. someone is always getting carried bridal style. it's a film noir. it's a rom-com. mutual pining slowburn. fighting side by side trusting someone with ur life daily and they know u better than anyone and ur literally soulmates but u can never be together bc u have to keep ur identities a secret and ur afraid they won't love the "real" you. amnesia and death and evil versions of eachother are extremely common but never permanent so u get the drama without the consequences. timeline is constantly changing and being reset so every au can be canon at once. *slaps roof of superhero universe* this bad boy can fit so many fanfic tropes in it
