Shen Ye, a game anchor who was born with no pain, was trapped in a mysterious mall that never stops. Here, every 72 hours, people are randomly swapped with other people or objects. While everyone was desperately trying to protect their identities, Shen Ye discovered that he could read all the pain memories of others in the past 24 hours by touching their bodies. In this cold concrete forest, pain became the only clue he could trust and the only way he could feel "alive". Until he met a girl whose body was covered with his fingerprints - every injury on her body was caused by Shen Ye himself. But Shen Ye didn't remember it at all.
