This play takes music as the main line, and reflects modern high school life and the passionate youth of high school students through the growth of student bands. Chu Tiange is a student of Nanhua High School. He loves music very much. On this day, he replaced the background music of the exercises between classes with his own original songs, which was an act against the heavens in a school that has always been known for its strictness. Chu Tiange's approach made the person in charge of the school's radio station calmly accept criticism, and also attracted the attention of Ye Feng, a classmate who also likes music. Chu Tiange and Ye Feng have completely opposite personalities, one is passionate and the other is cold, but they are both full of love and longing for music. Because the school strongly advocates quality education, inspired by the girl's school next door, Chu Tiange decided to form a band in Nanhua High School. Chu Tiange immediately got involved, but the band was formed without a key guitarist. Chu Tiange warmly invited Ye Feng to participate, but Ye Feng coldly refused. After going through some things, Ye Feng, who also loves music, loosened his heart, so he joined the band in order to avoid making up lessons. Ye Feng's arrival made Chu Tiange put aside the past misunderstanding and unhappiness between him and Ye Feng, and Calm Rong, who was arranged to make up for Ye Feng, also joined in later. The establishment of the band allows high school students with music hobbies and dreams to play the melody of youth together..
