The 28-year-old Liang Xia (played by Ni Ni) thought that she would be able to join hands with her boyfriend Mao Liang (played by Huo Jianhua) who she had been in love with for ten years and had been making various preparations to welcome their grand wedding. Her heart was full of beautiful fantasies about married life. Mao Liang's company was undergoing a tense second round of financing, and things were not going very smoothly. Liang Xia's desire for marriage brought great pressure to Mao Liang. One day, the two attended the wedding of Liang Xia's bestie Bai Xiaoning (played by Ma Su). Unable to withstand the romantic and warm atmosphere at the wedding, Liang Xia forced Mao Liang to marry her. What Liang Xia didn't expect was that Mao Liang actually asked for a breakup. Under the huge blow, Liang Xia collapsed. An accident made Liang Xia's mind return to the age of seventeen. At this time, she met a man named Yan Yan (played by Wang Dalu), who was mature in appearance but extremely naive in heart.
