小雪の朱－コユキノアカ－

Because of a raging snowstorm, school is temporarily closed. But, because the school's notice only went out on this very day, several students who aren't well-informed of the situation still end up showing up for school. The protagonist, Asou Shin'ya, is among them, too.

Although Shin'ya had prior received the information of the school's temporary closure himself, the next person in the contact chain, Izumi Aya, had already left the house and even though he wanted to complain and vent his anger about that later, he had to now chase behind her and ultimately attend school today.
