Time: 2024, late autumn
Location: Building 7, Xingfu Community, an old residential building built in the 1990s in the suburbs of Jiang City
Basic world view: This is a seemingly ordinary residential building, but each floor has its own unique rules. Tenants are told that they can live safely as long as they abide by the rules, but the rules themselves are full of strange contradictions. It is said that anyone who can stay alive for 30 days can have a wish come true.
