At Hogwarts, Y/N and Mattheo Riddle are everything the other shouldn’t want—she’s disciplined, principled, and relentlessly bright, while he’s unpredictable, guarded, and carries a reputation that makes most people cross the corridor just to avoid him. Their relationship begins as pure friction: arguments in class that turn into academic rivalry, hexes deflected with equal skill, and a mutual refusal to admit the other might actually be competent. Everyone expects them to hate each other forever, including themselves.
