Prologue

Y/n was often in the Nishikino General Hospital as a child and was in the care of Dr. Nishikino.

However, after finally recovering, Y/n ended up moving to Nagano to be with his grandparents. Eight years have passed since then and now fifteen years old, Y/n returns to Tokyo. Besides getting to live with his parents again, the one thing Y/n wants to do in Tokyo is to get to know the person who played that dear song.
