Ah Rong (Zheng Zhongji) is a 40-year-old single father. After his wife passed away unexpectedly, he took care of his son "Bao Long Ge" alone and ran a convenience store near his son's school. While relying on "Bao Long Ge", Ah Rong gradually became a warm man who knew how to love and give love. Because of the insurance purchased by his wife before her death, Ah Rong met his wife's insurance consultant Zhiming (Zhang Keyi). The two became good friends who talked about everything because of their various life experiences. Although Zhiming, who has a successful career, has long given up the idea of getting married, she is attracted by Ah Rong's warm and kind personality and rethinks the meaning of marriage. Ah Rong, a warm father, has helped many people and has formed an indissoluble bond with different women around him, but he has never let go of his thoughts about his deceased wife. As Ah Rong's relationship with these female friends becomes complicated, he also finds that he and Zhiming are gradually building a subtle tacit understanding.
