At Hogwarts, Y/N never expected to fall for Mattheo Riddle—the most dangerous, infuriating Slytherin in her year. He’s cold, possessive, and always watching her like she’s already his. What starts as hate turns into late-night secrets in the Astronomy Tower, stolen touches in empty corridors, and tension that neither of them can ignore. Mattheo swears he doesn’t care—until anyone gets too close to her. Because some rules at Hogwarts are meant to be broken… especially the ones about falling for him.
