I've been dying to try out this plot idea. I think it would be really cute.
So basically, they're in high school, seniors preferably. Muse A is an introvert, keeps to themselves mostly, has a couple friends, sarcastic, rude, I don't give a fuck personality. Muse B is more popular but has had a crush on Muse A for years. Since it's senior year they finally got up the courage to ask out Muse A.
Originally I was thinking that it would be a straight relationship, but now that I think about it, a gay relationship would also be super cute.
