At the award ceremony, Lin Yan found that another name was written on his certificate - Lin Yan.
A typo revealed tampered student status, blank custody records, and a warning hidden behind the school badge: Don't let him sign for you.
Subsequently, a gray van with the tail number 17 began to follow, and someone broke into the back door of the school. There was even an "identity confirmation" that Lin Yan had never signed at window 17 of the hospital. Even Xue Xinghai was involved in this identity mystery.
In order to keep their names, Lin Yan and Xinghai followed the No. 7 Iron plate, the forged payment slip, the incomplete household registration book and the clues left by Xu Qinghe, step by step to pursue the buried past. But the closer they got to the truth, the more they discovered that the real danger was not that someone was impersonating Lin Yan, but that someone was using a seemingly legal process to decide "who he was" for him.
When all records can be rewritten, what else can he use to prove himself? What kind of agreement is hidden behind that forgotten name?
