Lin Xingmian, a freshman in high school, noticed Jiang Yuezhi, a carefree, fun and cheerful sophomore in high school on the first day of school. He is a Linjiang boy who moved to Songxian City and is the head of the Propaganda Department of the Student Union. He laughs and plays with his roommates on weekdays, but he is always thinking about his grandparents in his hometown.
Lin Xingmian's parents lived in the United States all year round and he was raised by his grandmother. He has a lively and out-of-the-box personality. Her best friend Yan Zini enthusiastically assists her, and she discovers that Cheng Yizhou has a secret crush on her. Jiang Yuzhi's roommates often make noises, and as the head teacher's sister, he also inadvertently creates an intersection between the two.
During the three years of high school, the two met again and again on campus. They gradually got to know each other through their work in the student union and chance encounters between classes. A young heartbeat quietly sprouted, but they were still shy because of their youth. After going to school and being separated, after entering university, the two lost their ignorance, faced their inner love, and came together across time, composing a youthful love that began in midsummer and reunited after a long separation.
Purpose: Starting from the ignorant heartbeat in high school, it tells the story of the companionship and growth of boys and girls across time, depicts the forbearing preference and cautious temptation in youth, explains that the heartbeat of youth can withstand the precipitation of time, and the love that goes in both directions will eventually take root after growing up, praising the pure and sincere friendship and tender and long-lasting love in boyhood.
