Gu Shi'an, the chief physician at the Thoracic Surgery Department of the Municipal Hospital, has an elegant temperament. He often wears gold-rimmed glasses and sandalwood beads, and hides military-grade fighting skills. Li Feng, the actual controller of Southeast Asia Shipping Group, is sinister and mysterious, with a prominent scar under his right eye and suffering from congenital cardiac neurosis. Their story started when they collided in the emergency passage of the hospital on a rainy night. An unexpected discovery in the morgue and critical rescue in a dark alley gradually warmed up the relationship between the two. As they get along with each other, the Buddhist beads secretly reveal Gu Shi'an's life experience, and he actually has a deep connection with the Li family. In the end, after going through twists and turns, they stayed together in love, and the aroma of disinfectant and cigar blended together to write a chapter of happiness.
