Minaho and Yuichi have been married for five years, and in this time, she has been putting up with her husband's verbal harassment. One day Minaho falls ill. Despite this, Yuichi continues to berate her, and instead of worrying about her when she collapses and is rushed to the hospital in an ambulance, he swears at her. At this point, Minaho's patience has run thin, and she consults her male friend, Nanao, for advice. He tells her that she is too kind, and if she doesn't fight back, she'll be treated like a slave for the rest of her life. He then teaches her the secret to fighting in a marriage. Will Minaho be able to get out of the messy doldrums and be happy?
