The Host Club scrambles to find a way to prevent Haruhi's gender from being discovered during annual physical examinations. Their attempts fail miserably until Kyoya steps in with a doctor who promises not to reveal her secret. Meanwhile, Dr. Yabu enters the room searching for his daughter and is falsely accused of "making a pass" at a female student. Kyoya accurately assesses that the man's daughter is probably attending Ouran Public High School due to Dr. Yabu's story of financial difficulty. Tamaki provides him with directions and Haruhi is impressed by the club's insight and kindness, deciding to stick with them.
