Okumura is asked by his boss, Mizumoto, to be an answering machine while he is on a business trip. Unable to refuse, he accepts, and Mizumoto's wife, Yuna, is also at home. Okumura is nervous about spending several days under one roof. However, Yuna said, "I'm told to treat her as if I'm her master." Okumura is puzzled by the suddenness.
