Mattheo Riddle has a different girl on his arm every week, a permanent smirk on his face, and absolutely no interest in relationships. Then there’s y/n — the effortlessly beautiful Slytherin girl who refuses to be charmed by him. Their arguments become legendary around Hogwarts, filled with sharp banter, lingering stares, and tension neither of them wants to acknowledge. But when y/n starts getting attention from other boys, Mattheo realizes too late that jealousy is far uglier than rejection. Unfortunately for him, y/n has no intention of making this easy.
