Itsuki is a member of the art club, which has been too short on members for years to operate properly. When what other members it does have graduate one spring, leaving Itsuki alone, he decides to quit and let the club die with his departure. Until, that is, Otoha turns up to join. Itsuki can't just abandon this new student, but he figures that she'll probably stop coming before long, so he decides to stick it out for just a little longer.
