Jae Hee is a petulant, perfectionist, single architect. Cheerful girl Yoo Jin comes living next door. However, soundproofing problems between the neighbours has Yoo Jin stomping over to complain, but just in time to catch Jae Hee falling down in pain. Yoo Jin sent Jae Hee to the hospital in an ambulance. At the emergency ward they met Dr Moon Jung. A hilarious situation arose when Jae Hee had to receive an anal examination from his new lady doctor.
