In the future, memories can be bought and sold like data, but cannot be deleted.
Gu Nianzhen is the top memory appraiser in the industry. He is calm and restrained and firmly believes that "memory does not lie." He relies on instruments and data to distinguish truth from falsehood, and is recognized as the "eye of truth." Lu Li is a memory hunter in the black market. He is cynical and has countless people's memory fragments living in his mind. He relies on intuition to distinguish truth from falsehood, and works as a "scavenger" on the negative seventh floor of the city.
During an appraisal, Gu Nianzhen found a memory sample that was suspiciously perfect. After tracing, he found the supplier, Lu Li. The two got to know each other because of the confrontation of their concepts of "purity and impurity", but they didn't know that they were already entangled in each other's memories.
When Gu Nianzhen discovered that his core memory had been overwritten and tampered with, everything he relied on for survival began to collapse. The only person who can help him find the truth is Lu Li, who was labeled as a "defective product" by the system and whose mind is full of impurities.
In this world where memories can be tampered with, they exchange the most precious thing with each other - not the vows, but the memories that make up "me". And when everything can be fake, they must answer: Is the relationship between us real?
Purpose: Looking for truth
