The woman clearly desires Toru, but he does not give in to her advances. Toru’s behavior is peculiar. On the one hand, he chooses to stay with the woman late into the night, knowing what his continued presence will imply—to the woman, and to Kumiko. On the other hand, he shows restraint and does not have sex with her. Though he is not guilty of adultery, he is not entirely innocent, either, as he likely understands that his behavior will hurt Kumiko but goes ahead with it anyway.
