It's tough being Kaoru! When Tina invites everyone to Kyushu to visit the hot springs, he becomes a bit distressed that men and women are allowed to bathe together. After the wet and wild splash-fest, he returns alone to his room for the night...and Aoi pays him a visit. Later, Tina insists on getting some "alone time" with Kaoru. With all this pushing and pulling and splishing and splashing, will Kaoru finally begin to act like her boyfriend?
