On a rainy day in summer, the girl Jin Taixiu (Li Yinzhu) walks into the umbrella of the boy Xu Renyou (Li Bingxian) to take shelter from the rain, and the boy falls in love with her at first sight. The relationship between the two people in the university gradually warmed up, and on a rainy night, they quarreled and made up, and the feelings were too strong to be separated. The night before Ren you did his military service, he didn't wait until he promised to see him off, so he saved money. Seventeen years later, Xu Renyou has a happy family. His wife and youngest daughter make his life calm and peaceful. When he was teaching in a boys' school, he found that the behavior of a 17-year-old boy in his class was strikingly similar to that of that year, which brought back memories he had buried for many years. Only then did he realize that he could not forget. In the face of the feelings of benevolent friends, the male students also made waves in their hearts. I even broke up with my little girlfriend. It's too playful. Where is it? After the mystery of 17 years ago was solved, it was the ultimate love of life and death.
