Liao Chenxuan and Han Xinxi are trapped in an abandoned district that “chooses” its victims, where the exit changes at any moment, like a lie rewritten on the spot. To survive, they must learn to disguise themselves as part of its “rules,” mock death with dark humor, and use tiny details to fool the shadows hunting them. Each success only earns them a more sophisticated trap, and the true mastermind may be hiding in the way they look at each other.
