Akane Satomura is walking home from school one day with her friend Shiiko when she spots a young man she thinks she knows, though does not say anything to Shiiko. At school one day, she spots him again in the piano room, but once she gets there, finds that he is nowhere to be found. Another day while waiting in the vacant lot in the rain, the same young man appears and asks her if she is waiting for someone, but she runs off without saying anything. After meeting again a few more times, Akane eventually forgets about him.
