Lu Cheng was reincarnated and returned to the breakfast shop in 1975. He exposed Li Huiying's attempt to change the recruitment quota to marry a high-ranking cadre's son and refused, and even proposed to let her marry him. He was drunk and lying in a snow nest and was rescued by Lin Qingyan, but he regretfully witnessed her passing away from weakness. Later, he joined the train security team to arrest the theft gang and made meritorious service. In order to prevent Lin Qingyan from going to the countryside, he proposed an agreement to get married. After his master Xu Erye proposed marriage and obtained the certificate, he gradually fell in love after the marriage. While on a mission to capture enemy agents, he crashed into a car and fell into coma for three years to save his children. After waking up, he refused Lin Zhenfeng's offer to trade a courtyard house for a divorce and was accepted. Faced with the dilemma of his family being expelled, he opened a clothing store to confront Zhang Cheng and joined forces with the security team to expose the crime.
