The story takes place in a key high school in a small town in the south of the Yangtze River. It is centered on a small group of six boys and girls with distinctive personalities. In the three years from high school freshman to college entrance examination, they experienced the test of friendship, family conflicts, confused first love, and the choice between ideal and reality. They caused many hilarious and embarrassing incidents, as well as painful misunderstandings and separations. In the climax, after experiencing declining grades, conflicts between teachers and students, parents' divorce, and family changes, they each fell into a trough of growth. Fortunately, they resolved the difficulties one by one with the support of friendship and humor. In the end, the six people embraced their dreams and traveled across the country with their relief and love for youth. The story ended at the summer graduation ceremony.
