Sinopsis: In the early autumn of 2012, Yucai Middle School welcomes a cheerful transfer student named Su Zai Zai. On the first day of school, Su Zai Zai encountered with the aloof and cool Zhang Lu Rang and falls in love with him at first sight. Behind Zhang Lu Rang's seemingly outstanding academic performance and privileged family background, he is a "contradictory" person who appears to be quite confident on the outside yet constantly doubting himself on the inside. Due to the presence of his genius younger brother, Zhang Lu Li, Zhang Lu Rang is constantly compared to him by his mother. For over a decade, Zhang Lu Rang's life has been like living inside a thick shell. He is introverted and speaks little. He looks composed and polite but keeps everyone at a distance.
