Located in Zhehai City, Nancheng, the teaching building near the sea hides the chirping of cicadas and falling snow of youth.
In Class 1, Grade 1, the cool and top-notch Shen Yubai and the bright and cheerful Chen Zhiyu have been together for more than ten years. After the military training, the transfer student Lu Yan broke into this small circle with a cheerful attitude; in Grade 1 and Grade 2, separated only by a wall, the gentle and calm Lin Zhixia and the bright and innocent Su Wan have been inseparable friends since childhood.
The two groups of people were originally facing each other from a distance, but they completely crossed paths due to an accidental table sharing in the canteen at the beginning of the school year. Three men and two women sat around a table, and after a meal, they became a team of five who were inseparable from now on.
The idea: to accompany young people and gain sincere friendship and growth in ordinary youth.
