In the Mirror City, where memories can be "woven" and "erased", Lin Mo, the top memory weaver, takes it as his own duty to heal the trauma of others. By chance, he discovered a deeply buried fragment of his own memory - fire, screams and a woman he could not remember. In order to explore the truth, he embarked on a dangerous journey against the entire memory system, only to find that he was already a prisoner in the deepest part of this perfect city, and his forgotten past was the cornerstone of maintaining the false peace of the Mirror City.
