Y/N is beginning their fourth year teaching at Hogwarts and has quickly become a favorite among both students and staff. The only exception is Severus Snape, who seems to dislike them with every fiber of his being. Between sharp remarks, lingering tension, and constant disagreements, the two professors can barely stand being in the same room. As another school year begins, Y/N must navigate troublesome students, magical mishaps, and the ever-present challenge of working alongside the infuriating Potions Master—whether they like it or not.
