In the first OVA, "Sore wa, Ikinari Otozureta = Koi," we are introduced to Tarou Kabakura, a third-year high school student and captain of the boys' volleyball team, who is constantly pestered by his junior, Hanako Koyanagi, the girls' team captain. Koyanagi insists the boys give up the court because the girls have an important match approaching. When Kabakura refuses, she threatens to reveal his secret otaku hobby if he does not comply. Afraid his teammates will find out, Kabakura gives in and lets the girls use the courts, also offering her one-on-one training. As they spend increasing time together, their relationship grows into a close friendship.
The second OVA, "Tomodachi no Kyori," further examines the bond between Naoya and Kou.
The third OVA, "Shain Ryokou to Negaigoto," covers the happenings during the company retreat.
