In the near future, humans can peel away painful memories and store them in a central database called "Memory Island". Silence is a top memory organizer on the island, and his life is as smooth as a precision instrument. Until one day, a woman named Lin Yuan brought a broken memory - about a lighthouse in the rainy night. When Silence came into contact with this memory, ripples appeared in his frozen inner world. He discovered that this memory that did not belong to him contained the only key to unlocking his own past. In order to explore the truth, he resolutely stepped into the dangerous sea composed of countless forgotten things, and faced a secret that could subvert the entire world.
