The core anti-routine of this article is "two-way undercover and memory shackles". The heroine Shen Qingyi appears to be a famous Pingtan teacher, but is actually our hidden underground traffic officer; the male protagonist Gu Beichen appears to be a cold and bloodthirsty secret service chief, but in fact is our party's "lone goose" who has penetrated the enemy's heart. The two pretended to be a couple on a mission three years ago. They were both traumatized in an operation, and both had their memories of the other's true identity erased. Reunited three years later, he was ordered to capture her and she was assigned to steal the secrets from him. In the process of testing each other and using each other to the extreme, the two are constantly overwhelmed by the remaining memory fragments and the body's instinctive reactions. They are repeatedly torn between lies about identity and true feelings, until a shocking "Dupont Plan" pushes them to the edge of the abyss at the same time.
