Y/N is a 23-year-old Grade 1 sorcerer known for her rare cursed technique, Fortune Thread. By perceiving the invisible threads of probability woven throughout reality, she can subtly influence outcomes around her, turning impossible odds into possible victories. The stronger the change, however, the greater the cost. After a routine mission goes catastrophically wrong, Y/N and Satoru Gojo accidentally activate an ancient cursed object that does the impossible: It swaps their bodies. Determined to avoid causing chaos in the jujutsu world, the two agree to keep the truth hidden while searching for a cure. But pretending to be each other proves far more difficult than expected. As weeks turn into months, Y/N is forced to experience the crushing responsibility, isolation, and expectations that come with being the strongest sorcerer alive. Meanwhile, Gojo discovers the exhaustion, pressure, and hidden burdens Y/N has carried alone for years. The longer the curse remains, the harder it becomes to maintain the deception. Friends begin noticing strange inconsistencies, secrets become increasingly difficult to hide, and the line between their own lives starts to blur. Because sometimes the only way to truly understand someone is to become them.
