Lin Shanshan is a second-year student in the Chinese department at Fengshang Mixed Higher Academy. At T University, she meets Wang Shijie, a third-year finance student. Since they share the same interests, they soon become a couple.
Before that, Wang Shijie had met Bai Ling'er, a rich girl, online. The two called each other master and apprentice in a game. During holidays, he would even fly to her city to meet up, chat, and drink milk tea.
Wang Shijie told Lin Shanshan about this, too. Shanshan generously said she understood and didn't mind their relationship.
They thought things could stay this way until they graduated, but Wang Shijie's suspicious nature made him constantly doubt Lin Shanshan, and they soon broke up. Afterward, Wang Shijie went downhill, often eating, drinking, and making merry with some troublemaking students. He met Li Kai, the son of a partner company of his father's business, though the two had never met before. Li Kai liked Wang Shijie's younger sister, Wang Shiyan. Later, the Wang family went bankrupt, and the ruthless Wang Shijie insisted that his sister drop out of school and marry a spoiled rich playboy she didn't love. By then, Wang Shiyan and Lin Shanshan had become best friends. What will become of them?
