The chirping of cicadas in midsummer tears apart the silence of the small town, and Jiang Zhiyao's chance encounter with the white boy in the library kicks off the story. As the sound of cicadas fades away, the black and white keys of the piano room and the starlight exchange on the rooftop late at night. Those encounters that were thought to be coincidences have laid the foundation for them in the depths of time. What Ma Jiaqi guards is not only her memory, but also a long redemption buried in her heart. The cicadas will eventually stop chirping, but some heartbeats will bloom at the end of midsummer, flowers that will never wither.
