The wind in the third year of high school carries the fragrance of ink on the test papers, and also hides the most youthful throbbing in the hearts of young girls. Song Yien is a quiet and tough ordinary girl. She is immersed in books and papers, and just wants to spend her time preparing for the exam in peace. However, she encounters deliberate difficulties and bullying from her best friend Su Xiaojin for no reason. She has to swallow all the grievances alone, with no one to rely on.
Yan'an is a bright young man among the crowd. He comes from a privileged family but is taciturn. He never easily gets involved in other people's disputes. However, when Song Yi'en was most helpless, he calmly used his power to solve all the troubles for her.
An invitation that started out of kindness and a common meal together unintentionally revealed the little secret of a young boy's picky food, and brought two originally estranged hearts closer together. An unexpected gift of milk candy and a heart-warming and practical pine cone pillow concealed the girl's purest gratitude and care. It also made Yan'an, who had always been calm, experience a different kind of warmth for the first time.
In the depressing and hot senior year of high school, there were no grand confessions, only a steady stream of protection and two-way tenderness. He is her silent supporter, and she is the unique breeze in his heart. This ignorant love that started in the campus, like a green pine, quietly grows in the green years, pure and firm, and writes the cleanest and most touching heartbeat and companionship in youth.
