- Heroine: Lin Wei - She studied in the key high school "Ivy League Middle School" since her first year of high school. She comes from an ordinary family in a small town, and her grades are above average. She has low self-esteem due to her appearance (slightly fat, wearing thick glasses) and family conditions. She is extremely introverted, used to walking with her head bowed, and rarely takes the initiative to communicate with others. Her only hobby is hiding in the library and writing diaries.
- Male Protagonist: Jiang Yi - A classmate from a wealthy family, he is the focus of the campus. He has a sunny and cheerful personality, plays basketball well, and treats people sincerely. He seems careless, but in fact he has keen observation. He notices Lin Wei's silence but never despises her.
Those with low self-esteem can break their self-shackles through love and acceptance, find their own value, and reconcile with the world.
