As Hayato prepares for a major exam, Rin and Kei notice his bags under his eyes and take him to the nurse's office. Hayato is surprised to learn that Rin told Kei about his alleged cross-dressing secret (the misunderstanding from the previous episode), but collapses before he can do anything about it. Rin and Kei dress Hayato like a girl, but things quickly turn south when Kei offers her panties, Rin offers hers instead, and Hayato ends up waking to an unexpected sight.
