Yasuko was dissatisfied with her troubled married life. One day, she opened the door to hear a voice saying "It's delivery time," and when she went back to get her seal, she was attacked by the delivery man, Kenichi. In her fear, Yasuko was shown evidence that her body had reacted against her will, and was violated at his mercy. Kenichi took a picture of Yasuko, saying that he had asked him to. Then Yumiko came to see him, so Kenichi ran away. When Yumiko saw Yasuko naked, she realized that she had been raped.
