In a future city where memories can be accurately deleted, Lu Chen, an elite memory restorer, adheres to the creed of "memory is self" to help clients recover their lost past. A seemingly ordinary restoration commission involved him in a huge conspiracy. After the client Lin Ruoxi deleted the "trauma", she fell into deeper fear. There was a hole in her mind that could not be filled. After Lu Chen sneaked into her broken memory palace, he discovered that what was deleted was not a simple pain, but a living person and a truth that was deliberately concealed. He must fight against the giant "Wangchuan Technology" that provides "forgetting" services. While retrieving the truth, he also faces his long-standing pain.
