In Xinhai City, a future city where rain curtains and neon lights intersect, Lin Mo is a top "memory cleaner". With scalpel-like precision, he erases painful memories for his clients, while he himself is like an island, isolated from the ocean of emotions. When a mysterious woman named Su Wan appeared with a seemingly simple request - to delete the memory of a melody - Lin Mo's dusty past was quietly disturbed. That melody was actually the only reverberation in the depths of his forgetfulness. He discovered that his amnesia and the secrets Su Wan wanted to forget all pointed to a forbidden experiment called "Artemis Project". On the way to pursue the truth, he must decide whether to remain a slave to forgetfulness or embrace the sea of memory that can swallow him completely.
