In a small city, there is a school called Ma Zhong. In her first year of middle school, Class 1, the heroine Qiu Xia falls for a boy named Xi Wenjia, who is in Class 2 of his first year of high school. He feels the same way. Her best friend Zi Qi is always helping her along, and when they are in their second year of high school, Xi Wenjia finally confesses to Qiu Xia. After they get together, he tutors her, and they both get into Tsinghua University on the college entrance exams.
The rest is just a sweet romance (I'm too lazy to write it).
