In the "New Arc" of the future city where memories can be edited, deleted and implanted, the top memory architect "Zero" can build any perfect memories that are fake and real for clients, but he himself is a blank, deprived of all the past. His life is to find an island of self-existence in the false happiness of others.
Until a mysterious woman named "Mu" appears. She does not seek the illusion of happiness, but only seeks to retrieve a painful memory about a lighthouse that was forcibly erased. This commission will involve "Zero" in a huge conspiracy controlled by the giant technology company "Eternal Heart". When the two dived into the deep sea of consciousness, they discovered that Mu's forgotten memories were exactly "Zero"'s lost past. At the boundary between truth and falsehood, they must make a choice: embrace the cruel truth, or indulge in painless lies?
