The 33-year-old married woman, Akiko, is memorable for her innocent smile. She got married at 24 and, without cheating, found herself in her 30s, busy with child-rearing. There are glimpses of her earnest desire not to give up being a woman. Perhaps due to guilt, she stammers often, but between those moments, she also flashes a slightly naughty smile. Akiko forms a forbidden relationship in the fleeting moments before her husband returns. This is a record of the immoral acts committed in broad daylight and the lascivious behavior.
