One is Xu Renhe (Jang Geun-suk), the arrogant prince of the Department of Fine Arts; the other is Jin Yunxi (Lin Yuna), a beautiful girl of the Department of Home Economics. The two people who had no intersection met because of the bench in front of the Academy of Fine Arts on campus, and then got to know each other and fell in love. Renhe accidentally picked up Yunxi's diary, and got to know this warm-hearted girl in the diary, and the two came together. But because of misunderstandings and the intervention of others, this campus love ended in vain. Renhe and Yunxi each got married and had children, and they had not seen each other for many years. Thirty-two years later, Renhe's son Xu Jun accidentally met the girl Zheng Hena. The first impression of each other was extremely bad. What's more unfortunate is that Hena is Yunxi's daughter. And Renhe and Yunxi met each other again at this time. The two love stories are intertwined with the bitterness and helplessness of two generations. After misunderstandings and running-in, they finally ushered in a happy ending.
