In a future city where neon and fog intersect, Xinglan is a memory restorer who specializes in reconstructing memory fragments for those whose emotions have been wiped away by technology. She believes that every restoration is a glimmer of hope for strangers. But when she accidentally discovers that her memory has been tampered with and a certain emotion in her heart has been artificially erased, Xinglan begins to question - in a world where everyone can be rewritten by a program, does love still have real weight? She embarks on a journey to pursue herself and the truth, and meets a young man who is also troubled by memory. In the midst of each other's fragmentation and reorganization, they try to protect the purity of their emotions. The novel depicts the gap between artificial intelligence and human nature with delicate strokes, blends Xinglan's tenderness and tenacity into the cold tones of the future city, and explores how love and hope shine stubbornly in the torrent of information in the technological age.
