In the future city "Asselburg" where memories can be edited, deleted and traded, Ling Chen, a top memory weaver, uses his scalpel-like precision to erase the painful past for clients. He firmly believed that he was performing an act of mercy. However, his world begins to crumble when he comes into contact with the shattered memories of a mysterious woman, Alana - a sunny meadow that shouldn't exist. This memory invaded his consciousness like a virus, awakening forgotten visions. In order to explore the truth, Ling Chen embarked on a dangerous path, only to find that the skill he was proud of was just a screw in building a huge lie in the entire city, and his own past was the core of this lie.
