That summer, the anonymous musician “JIA” received a melody late one night that perfectly completed the chorus she'd been stuck on. The sender's name was “Light Source.”
By day, she was He Jia, a quiet, introverted top student. He was Zhang Zhenyuan, lead singer of the campus band. They met at a school music competition, and he invited her to write lyrics for the band.
He Jia had no idea that Zhang Zhenyuan was “Light Source.” Zhang Zhenyuan had no idea that the JIA whose work he admired was sitting right in front of him, revising his lyrics.
Their friends were also drawn together by music that summer: the supremely rational Le Xiaotong and the free-spirited musical prodigy Song Yaxuan, the aloof dancer Liu Qi and the gentle choreographer Ding Chengxin, and the social butterfly Wei Shiqi and the sensitive drummer He Junlin. Everyone had secrets of their own, and every relationship was like a song still waiting to be finished.
When the rainy season came, the echo would eventually find its source. A youthful symphony about music, growing up, and first love, played by eight boys and girls, quietly began to sound that same summer.
