In the future city "Fukawa" where memories can be extracted, stored and traded, Lin Mo, the top memory appraiser, is a man who has forgotten his past. His life was like a pool of stagnant water, until a mysterious woman Su Wan came to his door with a memory fragment that only carried "pure fear". At the moment of analyzing this fragment, Lin Mo caught a glimpse of a phantom related to his past. In order to regain his "self", he accepted the commission, but he didn't know that he was stepping into a huge conspiracy woven from memory. In this city where it is difficult to distinguish between true and false, everyone is an isolated island, and forgetfulness is a sea deeper than death.
