When Yunxiao was less than two years old, her parents divorced. At the age of fourteen, her mother suddenly died of illness, and she came to live with her father. Her arrival brought trouble to her father, who was a university teacher. In order not to affect the life of her father's family of three, Yunxiao lived alone in the single dormitory of the university. She overcame many difficulties and finally went to university. In the university, she met alumnus Gao Yuan, and the two gradually developed feelings. After graduation, Gao Yuan, who was committed to changing his family's predicament, had to return to his hometown to work due to heavy pressure from his family. The two are far apart, but still deeply in love. Gao Yuan's family insisted on letting him marry his middle school classmate who had been in love with him for a long time. Yun Xiao chose to break up with Gao Yuan under pressure from many parties, but Gao Yuan made a vow when they broke up: "I will not really give up until I see you find a happy ending." Five years later, Yun Xiao met Li Zijian, who had been in love with her for a long time. Gao Yuan, who felt that his career future was uncertain, lied to Yun Xiao and said he was married. Yun Xiao gave up and married Li Zijian and had children. Another five years have passed. After Li Zijian had a one-night stand with his subordinate, his female subordinate became pregnant and gave birth to a daughter. Yun Xiao chose to support him and his female subordinate. After the divorce, Yunxiao met Gao Yuan again and learned that he was not married that year. Gao Yuan became famous but was still single. The two cherished each other and eventually got married.
