Stupid AU idea (which I currently Just have genderswap drawings done lol)
So Casper lives in the old house from the 1995 Version and it has the Cast from the 1996 Cartoon. He's around 16-17 (everyone is in their teens). So He and Kat are in this between Not just friendship but not yet a relationship state, so a bit like a Friends with benefits situation but not as extreme (like with hugging and Kissing sometimes but not more). So Casp is pretty open for the relationship but Kat struggles, since she can't decide between Casper and that popular guy from the movie who's name I don't know atm.
Soon he (Casp) finds out that Kat thinks about an other guy as well which bummes him out pretty much. In school the teacher announces that there will be an exchange programm to another school and he decides to take part in it (bc of the sadness yadda yadda or I'll find another reason idk)
Well surprise surprise the school exchange brings him to Scare School. So he'll meet the most important ones, Lik
