In the future city "Eternal City", citizens use "memory weaving" technology to erase their pain in exchange for absolute peace. Lin Feng is the best memory weaver in the city. He trims other people's past with scalpel-like precision, firmly believing that he is the end of pain. Until one day, deep in the memory of a girl, he discovered a broken scene about an isolated island lighthouse that did not belong to her. This image haunted him like a ghost, awakening his deeply buried "phantom pain" that shouldn't exist. In order to explore the truth, Lin Feng embarked on a dangerous journey upstream and against the entire forgotten system. He will discover that this seemingly perfect city is built on an infinite sea called "Forgotten", and he himself is the last tower guard on that isolated island.
