The story begins at the start of the sixth school year at Hogwarts School of Witchcraft and Wizardry, in an alternate setting far removed from the linear events of the films. This year, tensions between the houses have reached a critical point within the castle, where social hierarchies, pride, and blood-purity prejudices dominate the students' daily lives. While the dungeons are controlled by a regime of arrogance and elitism led by Theodore Nott, Mattheo Riddle, Tom Riddle, Lorenzo Berkshire, and Draco Malfoy, the Gryffindor tower remains the core of resistance and loyalty.
At the center of this conflict is Ivanni, a pure-blood witch who, defying the expectations of her lineage, belongs to Gryffindor and is part of the inner circle of the Golden Trio and the Weasley family. Her academic and social life seems perfectly established among the lions until her path leads her to the darkest and most forbidden sectors of the castle at night. It is there, away from the eyes of her friends and teachers, that a magnetic, clandestine, and deeply toxic attraction unfolds between her and Theodore Nott.
From that moment on, the plot becomes a constant psychological tug-of-war. Theodore, characterized by his cynicism and silent possessiveness, struggles between sickly jealousy whenever he sees Ivanni interacting with other Gryffindors and the need to protect her in a subtle and lethal way from any threat or mockery coming from his own house. Ivanni, for her part, must learn to play a dangerous game of secrets and pride, where a single mistake in the hallways or shared Potions classes could expose their obsessive romance to the entire school, fracturing her loyalties forever.
