Lin Yuxiang lives in a small town in Shanghai. The only middle school in the town is one that values science over literature, which makes Lin Yuxiang's life very depressed. Although it is the third day of graduation, Lin Yuxiang's life has no goal. Later, the Chinese teacher in the class was replaced by Ma Debao, a young teacher of part-time literature. The two seemed to have a tacit understanding and soon became one. With the help of Ma Debao, Lin Yuxiang successfully entered the long-cherished literary society. In an activity organized by a literary society, Lin Yuxiang met Luo Tiancheng, who likes to pretend to be deep. They played with Shen Xier, a representative of the Chinese Department, and met the beautiful Susan by accident. The four of them had a good time together, and Candy Luo couldn't help being moved by Susan. Not long after, Luo Tiancheng wrote a love letter to Susan, but she was dismissed by Susan who was focused on her studies. Luo Tiancheng turned to have a brief love affair with a junior girl. Lin Yuxiang was glad to learn that Susan had rejected Luo Tiancheng. To his delight, his composition won the first prize in the national composition competition. In the cram school, Lin Yuxiang met Liang Zijun, a rich boy. Liang Zijun analyzed love for Lin Yuxiang and instructed Lin Yuxiang to chase Susan. Lin Yuxiang regarded him as a lover and did it one by one, but Susan always kept a lukewarm relationship with him. Lin Yuxiang clashed with some local ruffians while having dinner with Liang Zijun and Ge Fei. After the school was informed, Liang Zijun was forced to transfer to a private school in Pudong. After the final exam, the school arranged for students to go to Nanjing for "patriotism education". The night before going to Nanjing, Lin Yuxiang met Susan and Shen Xier, and they had dinner together. Lin Yuxiang was a little drunk, but he didn't have the courage to tell Susan. On the bus to Nanjing, Lin Yuxiang was lucky enough to sit with Susan. Have a good trip.

At this time, he learned that Susan, who had excellent grades, had not even been admitted to the listing key, so she had to retreat to the county key.
