It starts off with high school classmates Chen Xiaoxi and Jiang Chen, who have also been neighbors since kindergarten. Chen Xiaoxi, a cheerful girl who doesn't study much, is expressive about her admiration towards Jiang Chen, the popular guy known for his looks and high grades. Jiang Chen is also a guy who is very distant and indifferent towards people because of his father’s early death. Together, Jiang Chen and Chen Xiaoxi prepare for their Gao Kao, a university Entry Examination during their senior years in secondary school. Together with their classmates—the funny yet dirty-minded Lu Yang, athletic but blunt Lin Jingxiao, and cool national swimmer Wu Bo Song, they embark on high school life to university until their adult life.
