In the near future where memories can be edited and deleted, Lin Chen is the top memory weaver in the industry. He is calm and precise, treating memories as specimens that can be pruned, until he meets a mysterious client named Su Wan. She requested to delete a traumatic memory about the Sigma warehouse fire, but this name was like a key, accidentally opening Lin Chen's own dusty past. When he dived into the deep sea of Su Wan's memory, he found that what was burning in the sea of fire was not only her fear, but also his forgotten identity and truth. In order to find himself, he must salvage the self that the world has forgotten on this island of memory built by lies.
