In the "Dome City", a future city that is highly digitalized and where emotions are precisely managed, Lin Mo is a special "emotional restorer." He uses neural interface technology to sneak into the client's subconscious "rain realm" and repair the "emotional rifts" caused by trauma or stress. He has seen countless twists of sadness and anger, but he has always maintained a professional sense of alienation. Until a mysterious client "Suri" appeared with a "crack" that could not be repaired and emitted a strange blue light, Lin Mo's peaceful life was broken. He found that not only could he "see" Su Rui's memory fragments, but he was also attracted by a vivid but painful "reality" that he had never experienced before. During the repair process, he accidentally touched the core of the crack, and a fragment of memory about the "real world outside the dome" that had been deliberately erased by the Dome City officials poured into his mind. At the same time, the "Purifier", an official organization that specializes in erasing "illegal memories", focused on them. Lin Mo must choose between protecting Su Rui, guarding the dangerous truth, and his own professional creed.
