The stem of Nanwu University is to realize dreams, get into an ideal university and catch up with people you like. Nanwu University is a university praised by Duan and Sang Yan in The Secret that Can't be Hided. It is not a real university, but a university name invented by the author himself. Sang Zhi, the hero of the novel, had two wishes since he was a child: to be admitted to Nanwu University and to catch up with Duan, which were finally realized.

The novel mainly tells the story of a two-way secret love between the black-bellied Duan and the perverse Sangzhi. Sangzhi secretly loved Duan in her teens and often had nothing to amuse the hostess. In this way, the hostess wrote down her two dreams, one is to be admitted to Jardine Matheson University, and the other is to be commended.

For a short time, none of them talked to anyone, but soon the hostess was old enough to fall in love aboveboard, and the secret love between them was obvious, and the back was very sweet.
