You were in the piano club. There was a handsome guy named Nishimura Riki. He was very shy and reserved, but he was also very nice. You never heard him play because of his shyness, but your piano tutor said he played very well, which made you very curious to hear him play. One day, you were about to enter the room when you heard a beautiful melody... Who was playing? You opened the door a little and saw Riki playing the piano.
