"You're too serious... You should try wearing sexy lingerie and seducing your husband. You should be more conscious of being a woman." The words of the housewife next door casually muttered to Mika (Yuka Oshima) made her uneasy. Then, in the afternoon after finishing her housework, Mika picked up some obscene underwear that she would never normally wear and tried it on in front of the mirror. For the first time in a long time, she remembered herself as a woman, not a wife. However, she was accidentally seen by her husband's friend.
