UNiQUE

A and B’s child goes back in time to see how their parents got together because NO ONE WILL TELL THEM- turns out they’re the reason, oops?

AU A and B meet canon A and B. AU A and B are dating, canon A and B are not. Awkwardness ensues.

A and B go back in time. A tries to hide that they’re dating, but B wants SO DESPERATELY to be like, hey, that crush you have on A is TOTALLY NOT UNREQUITED LIKE WE THOUGHT, HOW BOUT THAT?

A has time traveling powers and keeps going back in time to rewatch the confession B gave every time they have a fight. B finds out and decides that whenever they fight in the future they’ll just use the same line they did then to make up so A will stop threatening the space-time continuum. (Bonus if it’s a really dorky or awkward line too, but A loves it anyway)

A has dimension-jumping powers and is mad that literally EVERY OTHER VERSION OF THEMSELF is dating B. Then B asks them out and is confused when A screams ‘FUCKING FINALLY, JACKASS!’

A and B’s child goes back in time because why the fuck do you have a time machine if you don’t want to use it? Past A and B scold their future child, before they’re like ‘WAIT, WE HAVE A CHILD?!’

AU A and B meet canon A and B. AU A helps canon A with their crush on canon B even though AU A doesn’t like AU B. (Whether they grow to like them or not is up to you)
