When a magical housing error places Fred Weasley and Y/N in the same Head Student quarters for their final year at Hogwarts, neither of them is happy about it. Fred thinks she’s uptight and impossible to live with. Y/N thinks he’s immature, infuriating, and far too comfortable invading her personal space. Despite repeated complaints to the professors, the arrangement can’t be changed. Forced to share a common room, study space, and living quarters, the two spend months arguing over everything from curfews to prank supplies. But somewhere between late-night conversations, accidental moments of vulnerability, and learning the sides of each other no one else sees, hatred begins to blur into something far more.
