In Xinhai City, memories can be read, repaired and stored. The top "memory organizer" Chen Mo can sneak into the depths of anyone's broken consciousness and piece together the truth, but he has only forgotten his own past. A mysterious commission leads him to a client codenamed "Evelyn", whose brain is a glass palace on the verge of collapse. In exchange for a "coordinate" pointing to his life experience, Chen Mo stepped into this dangerous sea of memory. Among the bizarre fragments, he not only had to fight against the vicious "guards" in the client's consciousness, but he also discovered that that forgotten history was inextricably linked to his lost past. The truth may be more cruel than forgetting.
