This is a love affair that started with a note. Twenty-three-year-old Shen Zhiyi has never experienced the darkness of society. She was raised by her whole family and believed that everyone in the world was a good person. Until the boss of the first company she worked for ran away, and she was taken to the police station to record a record. She met the cold-faced, few-worded police officer who helped her pick up the peace charm. After that, she was rescued by him when she was being followed in a convenience store late at night, and met him again when she got into a fight to seek justice for her best friend and entered the police station. The three encounters, like a script arranged by fate, pushed her little by little towards the man who was cold on the outside and hot on the inside - Ji Fan. Ji Fan is the backbone of the criminal investigation team. Both his parents died. His father, a policeman, died in the line of duty when he was ten years old. His mother also passed away three years later. He hid all his softness under that police uniform, not believing that he was qualified to love and be loved. Until Shen Zhiyi was like a spark, rolling into his cold world unexpectedly, catching him off guard with warmth.
There are the lights of a convenience store late at night, a tearful confession in front of a hospital bed, a life-threatening confrontation when being kidnapped by a criminal, and a policeman's determination to protect a girl with his life.
