In an apparently ordinary school, strange rules lurk beneath the surface, unknown to everyone. Gu Qi wakes from the aftershocks of a laboratory collapse and finds himself back three days before the cultural festival. Blood-red rules appear during morning runs, Yang Xin reveals her mechanical secret on dorm inspection night, and terrifying visions emerge in the mirror at midnight.
As the rules keep changing, his classmates start behaving more and more strangely. Can Gu Qi uncover the truth amid these complex, mind-bending rules, break the time loop, and stop Yang Xin from resetting the timeline? This strange school tale of rules and fate is waiting for you to explore alongside him.
So which world is the real one?
