In the near future, memories can be extracted, repaired and woven. "Memory Weaver" Lin Mo is a leader in the industry. He can reshape the most precious memories for his customers, but he has only forgotten his own past. An accident five years ago turned him into an island of memory. One day, a mysterious old man brought a broken memory chip, which contained only one scene: a crumbling lighthouse in a storm. When Lin Mo dived into this memory, he actually triggered the fragments that he had buried deeply. He discovered that his amnesia was no accident, and that the lighthouse was the only beacon leading to the truth about his past. In order to find himself, Lin Mo must sail into the dangerous ocean called "Forgotten" and face a secret that can overturn his entire world.
