In the Music Room After School

One day, as a consideration for my younger sister who is taking entrance exams, I had developed a habit of borrowing the piano in the music room after school three times a week to play and sing. That's when Yukimura senpai appeared—one of the academy's five (or maybe seven?) princes. This is a story about how a ditzy junior and a strong-willed senior who met by chance and are nothing alike somehow ended up becoming close friends. *A character who is somewhat like a reincarnated heroine from an otome game may appear.
