"Counter Tune" is a campus group portrait novel with two female protagonists.
Nanpu High School unified the breath of two thousand people with "B flat major tune", but the gap was opened by a sharp C sharp hit by freshman Chi Er. Her namesake, Guan Er, raised her camera and wrote the out-of-tune into the rhythm, widening the cracks into dark passages. They built a secret recording studio in the abandoned swimming pool of the music classroom, and let the heartbeat, electric drill, meowing cat and library magnetic strip perform a "C sharp uprising" on the same stage.
Concept: "True order is not imposed unity, but allows new frequencies to grow in the cracks."
