Synopsis：Shang Heyu ran away five years ago to avoid a family marriage and was picked up by Liu Shixi. Liu Shixi thought he had encountered an unexpected fate in life, so she worked three jobs a day to support him for two years. One day, Liu Shixi ran into Shang Heyu's conversation with others, only to find out that Shang Heyu had cheated on her. Liu Shixi divorced her husband and went abroad to study in a rage. Three years later, she returned to China to concentrate on her career, but she was unexpectedly pursued by her ex-husband Shang Heyu. Shang Heyu acquired the company where Liu Shixi worked and asked someone to take care of his wife Liu Shixi, but he was mistaken for Su Nian by his subordinates. People in the company mistakenly thought that Su Nian was the president's wife, so they tried to please her in every way, while Liu Shixi was made difficult in various ways. Su Nian also took advantage of everyone's misunderstanding and began to bully Liu Shixi. Fortunately, Shang Heyu showed up and helped her when she was bullied, but he was afraid that his identity would be exposed and he would not be able to win back Liu Shixi.
