She followed a favor into a girls’ washroom. She walked out holding another woman’s secrets. Yuu Koito only wanted to reclaim a meddlesome box of enchanted chocolates. Instead, she stumbles on Touko Nanami — Slytherin’s iron-clad prefect — with a broken time device and a bottle of Polyjuice potion. When the watch shatters, time hiccups: the same minutes loop, the same doorway eats them alive, and a single rule sews them together — stay within fifteen meters of the device or the day collapses. They bargain: Yuu will wear Touko’s face to handle the Slytherin schedule while Touko chases a fix. What starts as a humiliating favor becomes a race to stop a black-market potion ring, survive political knives in the houses, and undo a transformation that eats its owner alive. Each loop shows them choices they can’t take back, and each reset costs someone memory, reputation—or heart. This is a fanfiction of entangled loyalties, illegal magic, and slow, stubborn tenderness. Can two girls hold a stolen twelve-hour day together without breaking who they are?
