Chi Bai, the aloof, taciturn top student in his grade, meets Ji Yun, a gentle transfer student.
In a classroom on a rainy September day, a change of seats sets the story of two boys in motion.
In September, after an autumn rain at Mingde High School, the gentle transfer student Ji Yun joins Class 3 of Grade 10.
The homeroom teacher seats him beside Chi Bai, the top student in the grade.
Chi Bai is the aloof academic star everyone at school knows. He keeps to himself, maintaining a distance that warns others not to approach, and never lets anyone easily enter his world.
But his new deskmate, Ji Yun, has gentle features and faint dimples. He's like a warm breeze blowing into Chi Bai's unchanging life.
The desks are close together, and a secret flutter begins to stir in the hearts of the boys.
Theme: Two young people experience the shy, pure thrill of falling for each other. They gradually grow closer amid the ordinary routines of high school, in a gentle, healing story.
