Shi Yi and Pei Chuan were together in college and worked in the city bureau together. The two had been in love for seven years and were about to get married. However, during a team operation three years ago, Shi Yi "died" in an explosion due to Qi Xiao's mistake. After this incident, Pei Chuan and Shi Yi's brother Shi Jin fell out.
In the past three years, Pei Chuan used the pseudonym Qi Xiao to infiltrate the S Group as a police undercover agent. He persisted for three years and became one of the most capable assistants next to Boss Zhou. He met Zhou Zixuan, the eldest daughter of the Zhou family who is said to be studying abroad. Zhou Zixuan and Shi Yi have a somewhat similar appearance, except that Zhou Zixuan is the daughter of the S Group boss Zhou, and Shi Yi is the sister of the police officer Shi Jin.
