Lu Jinming is the captain of the anti-narcotics brigade in City B. He would not have any interaction with Bai Xin, the young lady of the four powerful families, but Bai Xin rescued Lu Jinming during an anti-drug mission.
From then on, people from the two worlds intersected. Bai Xin majored in psychology, which greatly helped Lu Jinming's anti-drug work.
But on the eve of the wedding, Lu Jinming died while participating in a major mission. Bai Xin spent five years in confusion, and returned to the criminal police brigade as a psychologist to help Lu Jinming's former friend take down the largest drug lord in Thailand, fulfilling Lu Jinming's wish and avenging Lu Jinming.
