Lin Zhixia, a "pseudo-sunshine girl" who is cheerful in front of others but harbors worries behind others, has a natural voice but can no longer sing in front of others.
The low-key and gentle musical genius Gu Shiyu is good at catching notes and can listen to people's hearts.
In the last summer before senior year of high school, an original music competition called "Summer Sound Wave" was held as scheduled. By chance, Gu Shiyu caught a glimpse of Lin Zhixia's hidden sparkle and vulnerability, and he extended an invitation to her: "Be my lead singer."
From then on, the empty music classroom became their secret base, with the sunset and the chirping of cicadas as their only listeners. He composed music for her and taught her to overcome her fears; she wrote lyrics for him, bringing him the most authentic emotional resonance. A melody that belongs to each other quietly grows in the sound of piano keys and heartbeats.
However, the shadows of the past are closely followed by the pressure of reality. When the lights of the finals come on and the audience is filled with people, can Lin Zhixia defeat her inner demons and let the world hear her voice again? Can Gu Shiyu compose the most perfect music of their youth?
This is not only a song about summer, but also a two-way journey about courage, healing and love. He spent a summer to find her voice; she spent her entire youth to become the most eternal inspiration in his melodies.
——Your voice is my only main theme throughout the summer.
Purpose: Explore how to face your inner fears, accept your imperfect self, and be brave enough to make your own voice. Emphasizing the healing power of love and companionship, it shows that youth is not only ignorant love, but also a journey of growth through the encouragement of others and self-struggle.
