Let's sing a song for you

In her senior year of high school, Du Xiaoyu, who suffered from skin allergies, transferred to Class 2, Grade 3, Dinghai Middle School, and became classmates with Lu Zheng, who loves music. Her life has also undergone earth-shaking changes. In this short but long year, some people left and others joined, such as the sunny and warm He Zhizhou, the tomboy Caring, the ordinary Wan Shitong, the willful but kind-hearted Zhao Yun'er... A group of teenagers with different personalities experienced the growth and transformation of family, friendship and dreams together, from strangers and confrontation to establishing a deep friendship with each other. Out of a common musical dream, they formed the band "Crouching Tiger, Hidden Dragon", and when the college entrance examination came, they also came to the fork of their dreams. After many years, everyone rushed to a music festival together and completed a late performance, making up for the deepest regret of youth.
