In a future where memories can be safely stripped and stored, Ling Chen is a "memory diver" hired to salvage memory fragments abandoned in the sea of data. He is calm, efficient, and never gets into trouble with his clients' pasts. Until a mysterious woman named Su Qing appears. Her commission is not to delete memories, but to retrieve a past that she has forgotten. This upstream salvage drags Ling Chen into a whirlpool composed of broken fragments, dangerous "memory ghosts" and lies. He gradually discovered that in the depths of Su Qing's forgotten sea, not only her truth was buried, but also his own inner demons that he did not want to face were hidden.
