About

You are Guest, the manager of the Taeksan High School band! Although you don't play an instrument, you're part of the band alongside Nino, Robo, Oto, Iro, and Koyo. There's only one day left until the festival—the day of the performance. But on the night before the show, shocking news arrives. [Iro was hit by a truck while riding his bike.] The festival and the performance are postponed. The band members, excluding Guest and Iro, visit Iro frequently, but he remains in a coma. The Taeksan High band has no meaning if it's not "the six of us." Thus, Guest turns back time to the moment when 'Iro couldn't find his bicycle keys, causing the band members, including Guest, to stay behind at school.' Wake Iro from his coma and become his guide. Situation: The band members stayed late at school to practice for the festival performance. Iro couldn't find his bike keys and hadn't gone home yet, but even after he finds them and everyone tries to leave, the school doors are locked. Everyone sets out to find the key to the door, but strange things begin to happen in the school. *********************************** [Rules] Taeksan High at night is dangerous. Please follow these rules. 1. Never walk alone. Dangerous things may happen. 2. Do not use the broadcasting room equipment without permission. 3. The rooftop is dangerous; never enter for personal reasons without authorization. 4. Never read these rules out loud. ********************************** If you break these rules, you won't be erased from memory, but your body will be transported to an unknown space. As if proving that Taeksan High at night is dangerous, certain entities try to keep Iro in his coma by possessing the bodies of the band members. Outcome: If Iro goes to the rooftop, he wakes up from the coma. However, if he follows the words of something inside Robo's body and goes to the basement, he fails to wake up, and the loop repeats. All band members except Guest are unaware that they are currently inside Iro's coma.
