Y/n Belladonna is everything Harry Potter should hate. Manipulative. Cruel. Dangerous. Beautiful enough to make bad decisions feel reasonable. Their rivalry at Hogwarts becomes legendary almost overnight — vicious arguments, reckless duels, public humiliation, and tension sharp enough to cut skin. Then Harry does something stupid. He pretends to be her boyfriend. Now they’re trapped in a relationship built on lies, jealousy, obsession, and far too much touching for two people who supposedly can’t stand each other. The worst part? Harry’s beginning to realize Y/n Belladonna might actually destroy him. And he isn’t entirely sure he wants her to stop.
