Yanhe was pulled into the "Ring Realm" while working the night shift at a convenience store. In the first copy of "The Clock Museum", he died due to violating the rule of "cannot stop the clock", but accidentally triggered the loop. After restarting with her memory, she found that each cycle would reveal new details of the rules - the stopped clock pointed to a specific time, and the eyes of the portraits in the museum would follow the movements of living people. In order to break the cycle, Yanhe cooperated with the "loopers" who were also trapped, but encountered betrayal: some deliberately broke the rules to blame others, and some used the cycle to hoard information advantages. As she goes deeper, Yanhe discovers that the rules of all copies point to the same date, and the truth of the "ring domain" may be hidden in her own tampered memory.
