Yuu agrees to keep quiet after discovering Meiko's secret. Ginta's cousin Tsutomu shows up to participate in a tennis game at his school.

Miki talks to Ginta in private about her feelings. Arimi tells a joke that makes Miki sad to think that she's no longer Ginta's closest female friend.

Ginta and Miki come up with a plan to take Meiko on an outing to cheer her up. When they invite Yuu to come along, Arimi asks if she can join them.
