On the first day of the third year of high school, the dean announced a new rule at the flag-raising ceremony: all sounds unrelated to learning were prohibited, including conversations during class, yawning, and the chirping of cicadas in midsummer.
"Quiet Committee member" Xu Qingqing discovered during his duty that Xu Chenzhou, the top student in the class, had no batteries inserted in his hearing aid - this boy who was always ranked first in grade actually relied on lip reading in class. The two formed a "Noise Resistance Army" in an abandoned music classroom, using the sound of piano to cover up the noise of skipping classes during evening self-study, until they discovered the truth about the "Mute Project" on the principal's computer: the so-called admission rate to prestigious schools was achieved by suppressing students' emotions with drugs.
On the eve of the college entrance examination, Xu quietly smashed the school's silent speakers, and three thousand imprisoned cicadas suddenly began to sing a deafening chorus.
When the dean roared and rushed into the examination room, Xu Chenzhou took off his hearing aid and heard for the first time the sound of this girl's heart beating like thunder for him.
