In the future city "Xinxu City", the job of elite memory corrector Ling Chen is to erase or modify painful memories for clients and maintain the "emotional stability" of society. He is a master of craftsmanship, but his heart is frozen by a personal tragedy that cannot be corrected. Once, he received a mysterious commission, and the target was a "false memory" in the mind of a girl named "Yi" that was contrary to official history. When Ling Chen sneaked into this island of memory, he found himself trapped in a time cage built of lies. The erased truth is not only related to the girl's fate, but also enough to subvert the foundation of the entire world.
