Natsumi, a housewife who can't even buy new clothes with her savings for the future, is disgusted with such days. One day, I happen to meet my friend's husband, Sasaki, on my way home. The two hit it off while being sent by car, and went straight to the hotel. Each other took off the ring from the ring finger of the left hand and devoured the body like a beast without taking a shower. Another day, his neighbor Sakamoto came to visit Natsumi's house and said in a low voice that he had witnessed an affair.
