Seventh year. One stupid decision. One experimental Weasley invention. One week where nobody at Hogwarts can lie. When Draco Malfoy accidentally unleashes an unfinished joke product from Weasleys’ Wizard Wheezes, the entire castle is hit with an ancient truth enchantment. For seven days, every witch, wizard, ghost, portrait, and professor is incapable of telling a lie. Secrets unravel overnight. Crushes become common knowledge. House rivalries explode. Years of resentment finally boil over. And the Slytherin friend group quickly discovers that keeping quiet isn’t nearly as easy as they thought. Y/N and Mattheo Riddle have spent six years insisting they’re just friends. The truth curse has other plans. As confessions become unavoidable and the entire castle descends into absolute chaos, one question remains… Can the truth bring people together… Or will it destroy everything they’ve been trying so hard to protect?
