On the day of entrance exam someone helps Narumi by giving her a pencil. She wants to thank him but he's soon gone. She couldn't forget her hero so she hopes to see him again. While looking around the campus she hears the sound of the piano and enters a room where other four freshmen are present. Here she'll meet Seika, Tamotsu, Osamu and Junichiro. Together they decide to form the Asunaro Club.
