Top student Liu Shuci arrives at a brand-new school, most of whose students have come from its affiliated junior high. On the first day of school, he unexpectedly runs into Chen Zaifa, the "idiot" he met over summer vacation. The two are forced to become desk mates. Over their three years of high school, they grow together and pursue their dreams, secretly watching the people they like, confessing their feelings, and repeatedly coming close to love without ever quite reaching it. Through all the ups and downs, they grow together and gain a friendship.
