Hermes was specially selected by Royal (Jian Yi), the manipulator behind the scenes, to join the R plan to "save" Jian Liang. Going back to the past, Hermes originally wanted to kill Jian Liang directly, but through long-term relationship and understanding, Hermes discovered that things were not as simple as imagined. Shan... Jian Liang's life experience is far more tragic than imagined, but Jian Liang's ruthless massacre of his family made it difficult for Hermes to make a choice. In the end, Xu Zhichen's inner kindness and sympathy outweighed revenge and decided to help Jian Liang, using warmth to influence Jian Liang and help Jian Liang walk on the right path. Through investigation, Xu Zhichen discovered that Jian Liang's father was an undercover agent, and her parents were high school classmates. The two got together after Jian's father went to the police academy. After Jian Liang's father graduated, he joined the special forces. Just when her mother was pregnant with Jian Liang, her father was sent to work as an undercover agent. The mission was to obtain a piece of drug and arms smuggling information held by a major drug lord, but an accident occurred. In a melee between drug dealers and the army, Jian Liang's father's identity was exposed and he was eventually killed by a drug lord. The vital information was obtained by Jian's father. For the safety of this information, Jian's father hid it. Although the drug lord was arrested, the whereabouts of the information hidden by Jian's father has always been unknown. In order to prevent the information hidden by Jian's father from being found by the escaped drug traffickers, the State Bureau did not disclose the true identity of Jian's father. After some "operation", Jian's father was included in the list of publicly captured drug traffickers, and he actually became a heinous drug trafficker as others said. Jian Liang's mother was raped and murdered by the only drug trafficker who escaped, leaving her body on the street. The escaped drug traffickers were caught by the police because of the atrocities they committed against Jian Liang's mother. Jian Liang, who lost her parents, and her grandmother have been living in the most chaotic slums, and are harassed by some gangsters every day. Jian's father's superiors turned a blind eye to this, as if Jian's father was really a heinous drug trafficker...
