In the future city "New Island" where memories can be extracted, traded and tampered with, Ling Chen, a top memory fabricator, makes a living by repairing damaged memories. He is calm and professional, and regards memories as cold data. One day, a mysterious woman named Yi Shu brought a box of memory fragments that were too broken to be recognized, and entrusted him with a taboo "deep reorganization." While piecing together this island of memory that was full of danger and sadness, Ling Chen was horrified to discover that his forgotten past was lurking beneath the stormy waves of this sea of memory. Not only was he a restorer, he was a key part of this lost history.
