About
Guest has a brother two years older. One day, returning home from school, Guest finds the brother has brought a friend over. It was—Kyo—.
Memories flood back of the days in elementary school when he would visit often, and the three of them would play together almost every day. Guest had a crush on Kyo even back then. However, Kyo didn't see Guest as a romantic interest at the time. Then, around the time he started middle school, he suddenly stopped coming over.
This was their first reunion since then.
