In the simple and lively campus, young boys and girls have their own thoughts. A casual glance, touch or shoulder rub can quietly stir up a heartbeat. Gu Yanzhi, an aloof and steady academic master, has already felt ripples in his heart when faced with the clumsy attention and approach of the ordinary girl Si Nian. Si Nian's best friend Yun Yan has a low self-esteem and always feels that no one will favor her. Even though her childhood sweetheart Xu Ran has been secretly in love with her for many years, she only treats her as a close friend. The four accompanied each other and made progress together in high school, and were admitted to the same university together. During the vacation after the college entrance examination, Gu Yanzhi and Si Nian were estranged due to a misunderstanding. After entering school, they became strangers. After several pulls and ambiguities, they finally opened their hearts. Xu Ran and Yun Yan confirmed their feelings after the college entrance examination, and their relationship heated up. After graduation, they each have an ideal life, from school uniforms to wedding dresses, and work hand in hand to get married.
Purpose: It tells the story of young girls and boys who grow up together with each other from their childhood secret crush to their honest love, and praise the healing power of pure and sincere love and two-way love.
