Wuyu Island is immersed in the cold and wet sea fog all year round. Shen Lin guarded the frontline case files of the Criminal Investigation Detachment for seven years and became the sharpest captain of the detachment. As one murder case after another piles up, the airborne top forensic doctor Su Yan crashes into her field of vision - she is the crush she deeply buried in her heart and missed in high school.
The heartbeat of youth ended hastily, and we reunited at the autopsy table and the crime scene after many years. One person chases the murderer through the dark corners of the city, while the other cuts open the cocoon to restore the testimony of the deceased. Shen Lin hides the feelings that have never dissipated, and only works side by side as a partner, using the case to get closer, and staying with each other based on tacit understanding.
The sea fog rolled in, murders occurred one after another, they spent countless mornings and evenings together investigating cases, and countless late nights searching side by side. They survived numerous life and death difficulties, but ultimately failed to cross the gap between reality.
Morning light and dusk alternated back and forth. The two of them had spent countless difficult mornings and dusk together, but in the end they could not spend the rest of their lives together. Only the long sea breeze on the foggy island was left, recording the regret of a life that ended without a cure.
"You liar!"
"Didn't you agree to marry me? Didn't we agree to get married?"
"Everything you promised me doesn't count."
Intention: Mission comes first, personal feelings can only give way.
