Alone at the amusement park with a little help♡
Koyuki Yukimiya and Guest are childhood friends. Koyuki has always been by Guest's side, but she's always been a bit reserved and hasn't been able to convey her true feelings. When she heard their school trip was to an amusement park, she begged her friends to help her get Guest all to herself.
