Li Tiantian, who is in her freshman year, met Zhang Xuan, who was four years older than her, because of an internship arranged by the school. Zhang Xuan's various experiences made her curious about Zhang Xuan, and Zhang Xuan's enthusiasm also made her feel a different kind of warmth during the internship. A few months later, Zhang Xuan took the initiative to meet Li Tiantian. During this meeting, Li Tiantian met his good friend Liu Yuhang. Liu Yuhang fell in love with Li Tiantian at first sight. He wanted to muster up the courage to pursue Li Tiantian but found that she was already Zhang Xuan's girlfriend. From then on, he chose to guard this secret silently, and assisted Li Tiantian and Zhang Xuan, helping them overcome difficulties and get closer to each other. Li Tiantian kindly brought her roommate and Liu Yuhang together, but ended up having a tense relationship with her roommate. Finally, after several young people experienced various emotional ups and downs, Liu Yuhang got his own girlfriend, and finally watched Li Tiantian and Zhang Xuan enter the marriage hall. However, after the marriage, Zhang Xuan went bankrupt due to gambling and Internet loans, and Li Tiantian grew up from his former girlfriend to the mainstay of the family. During this period, Liu Yuhang's help and encouragement, as well as his family's company and support, worked together to save this unfortunate family. Zhang Xuan also saw clearly the most important things in his life because of his mother's death.
