Looking for Dark Academia enemies to lovers slow burn

Hello! I’ve been looking on this subreddit for a while and have barely found any books for this. I’m looking for an enemies to lovers book where they genuinely hate each other, like to the point that they try to kill each other. I want it to be in a Dark Academia setting. I don’t care if it’s (professor x student) or (student x student). Also it would be amazing if they were enemies about 80% of the book and then lovers the other 20% as when they stop being enemies I feel like it drags so much.

Hard no’s: no HEA, age play, incest (step brothers is okay)
