In a medium-sized city called "Linyuan City" on the southern coast, there is a special phenomenon unknown to the public - "remnants of memories." This phenomenon is not a supernatural force, but stems from the unique geological structure underground in Linyuan City. The special minerals contained in it will "burn" part of a person's memory fragments into the surrounding environment under certain circumstances (such as strong emotional fluctuations, unexpected deaths, sound waves of specific frequencies), forming an existence similar to a "memory imprint".
"Residual memories" are extremely hidden and cannot be sensed by most people. Only a very small number of people who are born with a weak resonance of the hippocampus of the brain and the frequency of this mineral can "read" these residual memory fragments under certain conditions. These fragments are often fragmented and non-linear. They may be a conversation, a scene, an emotion, or even just a vague picture. They are easily interfered by the reader's own memory, causing "memory confusion."
