The elevator fell out of control late at night. When Shen Zhiyan opened his eyes, he was already standing in the corridor of the "Threshold Apartment" - this is the transfer station between reality and weirdness. Each tenant must go to different ghost story worlds on schedule to complete tasks and use points to pay "living rent". She was thrown on the last midnight bus with a group of strangers: some looked on indifferently and only stretched out their hands at key points; some were shaking and biting their tongues; some were as familiar with the rules as the administrator, but stood on one side of the apartment. In the ever-escalating missions, they passed through ghost buses, wishing villages, ancient houses with dismembered corpses, and diary mazes... Artifacts exchange for survival at a price. The rules are never complete. The real fatal thing is never monsters, but the cracks in the human heart. Three pairs of relationships slowly took shape in the blood and truth: the calm female tenant and the gentle old resident went from cooperation in interests to concern for each other; the noisy work partners learned to fight side by side in mutual harm and defense; the former lovers met again, but they could only leave a way out for each other on opposite sides of the rules. When they finally get to the secrets of the Liminal Apartments, there's only one question left - should they go back alive, or stay and become the never-seen gatekeepers in other people's stories?
Intention: Under extreme fear and high-pressure rules, people can still maintain themselves and softness; the real choice is not "life" or "death", but in the forced game, fighting for a life without regrets for yourself and others - even if the ending is that meeting each other is worse than missing each other, you must say your farewell with sobriety and tenderness.
