Shen Mo is the manager of "Twilight Apartment". He is gentle and patient and deeply trusted by tenants. But the apartment's tenants never really leave—they sign a contract to live forever, trapped in a seven-day cycle. Shen Mo's task is to maintain the order of the cycle and collect the "time fragments" generated by tenants in the cycle, which are used to maintain the existence of the apartment. Until the new tenant Lin Che (25 years old, memory detective) moves in and begins to notice time anomalies, an endless game about memory, contract and escape begins... And the secret of this apartment is far deeper than the cycle itself.
