The protagonist Yang Rongqi entered the university as a "self-taught candidate" at the invitation of a beautiful teacher, and then met five students who, like him, were eliminated from the college entrance examination. They are Chen Keren, Lian Zixin, Sun Xiaocai, He Daoyu and Zuo Tianbao. In order to successfully obtain their undergraduate diploma, the six of them started a three-year struggle. They went to the library to review together every morning until the library closed at night. However, things are not that simple. First, Zuo Tianbao was ordered to drop out of school due to his irrational behavior. Then He Daoyu also chose to drop out in order to pursue a different life experience. Later, Sun Xiaocai and Lian Zixin also chose to drop out in order to pursue an ideal life. Faced with this situation, the protagonist Yang Rongqi also had an idea, and he did not want to continue reading. But later, under the persuasion of his head teacher, he chose to stay. In order to fulfill the instructions given to him by his class teacher, he began to look for the ultimate goal of education mentioned by Tagore.
