The Republic of China. The suburbs of Shanghai. The Jian family is a declining country gentry family. The four beautiful daughters with different personalities are all waiting to be married. Mrs. Jian's greatest wish is to marry them to wealthy families. The rich sons Ding Zihui and Song Wenxi arrive, and a battle for a son-in-law spreads in the small town of Jian's family. The most beautiful eldest daughter Rujing wins the heart of the gentle and friendly Ding Zihui, and the most opinionated second daughter Rutian is prejudiced against Song Wenxi, the "number one rich son-in-law", because of his arrogance. Rutian and Rujing leave the small town and come to Shanghai. Wenxi "feels bad" with Rutian several times, but finds that he has fallen in love unknowingly. Unfortunately, there is already a candidate for marriage around him-Cheng Biruo, who saved his life. He can only bury his affection for Rutian in his heart. After entering the city, Rutian is obsessed with Liu Tianyu, a popular officer who has met several times. The history of Wenxi and Tianyu's rift is also known by Rutian. Tianyu is suspected of murder and arrested. Rutian finds Wenxi to save Tianyu. Facing Rutian's request, Wenxi rescued Tianyu despite the pain in his heart. Wenxi couldn't restrain his true feelings and finally confessed to Rutian. However, at this time, Rutian had a deep prejudice against Wenxi due to various misunderstandings, and immediately rejected Wenxi's arrogant confession with a sense of charity. Liu Tianyu changed from a soldier to a comprador, and got closer to Birao's mother and daughter. In order to stop the development of Wenxi and Rutian's relationship, Birao allied with Wenxi's enemy Liu Tianyu. Tianyu used his lover's plan to Rutian, and Rutian was deceived by Tianyu. At the critical moment of Tianyu's proposal, Wenxi appeared and exposed Tianyu's behavior of abducting his sister Wenxuan and causing her to become pregnant. Rutian woke up and Tianyu failed. Tianyu once again used the innocent Wenxuan to frame Wenxi and pushed Wenxi into a trough from which there was no return. Rutian used her intelligence to find evidence that Wenxi was innocently victimized. Wenxi gradually regained his lost ground, and Tianyu was finally overthrown. Wenxi learned of Rutian's contribution, and the two happy enemies finally did not miss each other again. Mrs. Jian's wish to marry her daughter off was finally fulfilled.
