In the future city "Mirror City" where memories can be accurately deleted, Ling Su, a top memory cleaner, makes a living by erasing the pain of others, but is trapped by the repeated broken illusions in his own mind. A commission that breaks the rules draws him into the whirlpool: the mysterious woman Su Wan does not want to be forgotten, just to find a memory that has been "erased". When Ling Su dived into the depths of Su Wan's confused memory, he discovered that her past actually overlapped with his own illusions. Under the glory of the Mirror City, there is a huge conspiracy to tamper with life, and he himself may be the most critical prisoner in this maze of memory.
