When the world begins to abandon you, memory becomes the last beacon. But the lighthouse also goes out.
Archivist Fang Li accidentally obtained a strange blue notebook with the words "Everything is Memory" written on the cover. He discovered that through this notebook, he could read, modify and even steal other people's memories. But every time he uses it, part of his own memory disappears. When a young woman cries and asks for his help in retrieving her erased childhood memories, Fang Li becomes involved in a series of bizarre disappearances - each victim has lost all memory except for one thing in common: they all had access to a blue notebook.
As the investigation deepened, Fang Li discovered a mysterious organization called "Memory Pawn Shop". They secretly collected specific memories and weaved a memory reorganization plan covering the entire city. The most disturbing thing is that Fang Li began to see fragments of his life in his memory fragments - a girl wearing a white dress appeared repeatedly, and his notebook records showed that this person did not actually exist...
When reality is reshaped by memory, and when he becomes the strangest stranger, Fang Li must find the truth in this memory game before he is completely forgotten.
