Qi Zhou, in his early thirties, is the owner of a second-hand bookstore in Linjiang City. He raises his five-year-old daughter Xiaoman alone. This small town with simple folk customs hides a "memory rift", and some people receive fragments of past lives. He often has strange dreams and unbearable headaches, but he doesn't know that he has experienced three lives.
The newly moved archivist Wen Lingyi is cold and taciturn, but is actually an elder of the Shouyi people. He remembers the bond with Qi Zhou in every life. She noticed that Xiaoman's emotional fluctuations were causing the rift to expand, and the crisis was quietly approaching.
The Memory Keepers organization warns not to touch the memory, but the traitors behind the scenes are closing in step by step. The father and daughter's daily instant noodles, picture books, and pick-up room contain clues to changing time and space.
No golden fingers, only warmth and daily truth. A family of three work together to solve a mystery and find each other in the fog of memory.
