In Xinhai City, shrouded in neon and rain, Ling Su, a top memory fabricator, can sneak into other people's brains to repair or erase memories. He was like a soulful watchmaker, calm and distant, until a mysterious woman named Su Wan came to his door with a seemingly simple commission - to erase the memory of a car accident. When Ling Su dived into that broken memory, he discovered a reflection that didn't belong to her, a shocking secret that could overturn the entire city. This commission was like a broken mirror, not only reflecting a deadly conspiracy, but also illuminating his own long-dusted past. He is forced to make a final choice between the comfort of forgetting and the pain of remembering.
