I’m super tired of the trope where the heroine ends up with the first guy she meets. It’s annoyingly predictable and boring to me at this point so I’ve been looking for some stories that don’t follow that format. Can anyone think of some where the heroine ends up with a different guy than who it seems like it’ll be at the beginning? Thanks!
