On a snowy night, newborn Yang Qixue was abandoned by her parents in front of the orphanage because of a congenital heart. Yang's mother took her in and raised her in the orphanage. When he was eight years old, entrepreneur Ling Xiao came to the welfare home to express condolences. Yang's mother begged him to help Yang Qixue complete the first stage of heart surgery. At the plea of his son Ling Wenyu, Ling Xiao finally agreed to donate the surgery money.
Yang Qixue remembered Ling Wenyu's kindness and secretly vowed to repay her kindness when she grew up. A few years later, Yang Qixue was adopted by the family of a primary school teacher in Chengdu and was admitted to university. The year she graduated from college, she gave up recommending graduate students and insisted on coming to Hangzhou, where the Ling family's company was located, looking for Ling Wenyu everywhere.
By chance, Yang Qixue applied for a job as a nanny in the Ling family, and took care of Ling Wenyu with all her heart, in order to repay the favor of saving her life. Due to the lack of maternal love when he was young, Ling Wenyu was introverted and withdrawn, and was estranged from his biological father. After experiencing many struggles, they fell deeply in love. It was here that Ling Wenyu's college girlfriend Su Yan returned to China and used various means to finally force Yang Qixue to leave the Ling family.
After leaving, Yang Qixue couldn't let go of that love. She turned into a cleaner and joined Ling Wenyu's Tongyu Company, and established a friendship with Qian Kai, the company's sales director and Ling Wenyu's classmate. Su Yan disguised herself as Yang Qixue, deceived the drunken Ling Wenyu, had a relationship with him, and became pregnant. At the wedding, Yang Qixue fainted due to excessive sadness. . . . .
