The drama was adapted from the novel She's a Little Crazy by Zhu Yi, and stars Zhou Yiran and Zhang Miaoyi as both male and female leads respectively.

In the early autumn of 2012, Jiangyi High School welcomes a cheerful transfer student named Su Zaizai (Zhang Miaoyi).

On the first day of school, Su Zaizai encounters the cool and aloof Zhang Lurang (Zhou Yiran), and falls in love with him at first sight.

Behind Zhang Lurang's seemingly outstanding academic performance and privileged family background, he is a "contradictory" person - someone who appears to be quite confident on the outside, yet constantly doubts himself on the inside.

Zhang LuRang and Su Zaizai work towards their goals while supporting one another, as romance begins to blossom throughout their friend group.
