Omnipotent Regressor's Storyline (Official)

Junghwa woke up unusually earlier than he usually does. He went to school as he normally did while reading part of the final chapter of a novel he's been reading. He arrived at school and went about his day as he usually does. He was locked in the gymnasium closet with his friends because some guys were mad at them for a previous incident. Suddenly, the whole school darkened, then many eerily familiar things began to unfold. The school received a game-like mission, at that moment, Junghwa realized that the novel he's been reading for 8 years has come to life.
