Su Hao is a Chinese teacher at Dongting High School in Yancheng, Jiangsu Province. Because he helped a sick teacher in his senior year of high school to teach, he had an emotional entanglement with Wang Yifei, a student in his class. Just when their relationship was on the right track, unexpected changes occurred as Wang Yifei entered college. At this time, Jiang Yuan, who returned to his hometown of Yancheng to worship his ancestors during the New Year, unexpectedly broke into Su Hao's peaceful life. As the two gradually understood each other, Jiang Yuan became interested in this somewhat aloof Chinese teacher, and came to Dongting High School to become a substitute physical education teacher. In this key high school, with the arrival of the young master, an unexpected story happened. Su Hao and Jiang Yuan also turned from misunderstanding to knowing each other and falling in love. However, what they faced was by no means a smooth and beautiful life. There were many difficulties and obstacles that tested the relationship between the two.
