Enzhi (Ren Changding), an elderly college student who has completed his military service, is studying in the law department, and the campus is full of young men and women who are curious about sex. Unfortunately, because of his simple appearance, he doesn't have much affection for women, and his brain is not very good. By chance, Enzhi got to know the top member of the school fitness club, the beautiful woman Yinxiao (he Zhiyuan is acted the role of), and he was immediately attracted by each other's beauty. Enzhi tried his best to get into Silver filial piety and win favor, but it all ended in failure, and even caused a lot of misunderstandings. For example, on the bus, he was kicked by Silver filial piety as a pervert. Later, Yinxiao captivated the rich playboy Xiangxu (Zheng Min), and even got pregnant, but was finally abandoned, sad and desperate. At the same time, there has been a subtle change in the industrial relationship between Enzhi and Yinxiao.
