honestly I love angst but I need it to have a happy ending
there are actually basically two reasons for this:
1. Strictly-fictional catharsis. I like characters in bad situations because I like to see them overcome those situations.
2. There are plenty of situations in reality that can’t or don’t have happy endings, or even endings that could qualify as bittersweet. But in stories? Heck yeah, the characters can find happiness after struggling. So a more real, personal sort of catharsis from that end.
