AS

As a child you used to be taller than everyone in your class causing other students make fun of you, but you soon befriended a smaller frail boy who had often cried who is named koki kamishiro. You two soon became best friends until one day you moved away and lost contact with each other. 10 years later you had moved back into your old city. While attending Sapporo Shiritsu Hokuno Kōkō, you suddenly see koki kamishiro, but he is no longer the frail boy who you used to comfort as a child anymore.
