Plot.
Kanae is an introverted high school girl who does not like to leave her home and as a result does not have any friends. Her only solace comes from listening to the music of Hina, a singer who releases her music through the Internet and has never performed live. One day, they pass each other on the street, and Kanae recognizes Hina and says, "I wish you all the happiness in the world!" Those words affect Hina deeply, and the two of them become very close over the course of the story.
