It is a story about a girl who is inexpressive but careful and sensitive and a girl who is very ambitious but has little self-control and supervise each other's progress.
After his parents divorced, Li Yusheng transferred to the school where Ji Yuan attended. Ji Yuan was very curious about this boring person and wanted to attract her attention and talk to her. Li Yusheng also went from being indifferent to Ji Yu'an at the beginning to gradually getting used to the presence of a chattering person around him.
As they got along, Li Yusheng discovered that Ji Yuan was actually a girl who wanted to make progress, but she had always been influenced by the outside world. Yusheng, who had not been taken seriously since childhood, had long been accustomed to isolating the noise of the outside world. She decided to help the girl and urge her to study and improve.
Similarly, Ji Yu'an discovered that Li Yusheng's inner self was not as good as her appearance. Yusheng was eager to be valued and firmly chosen, so Yu'an decided to treat her as his most important and closest friend.
