Ryona has been married for two years. She was supposed to be enjoying a happy life with a man she met at work, but she has come to suffer from her husband's verbal abuse. At first, she wanted to support her husband, who was worn down by work stress, but as the days went by, she could no longer bear the increasingly severe emotional abuse and decided to go back to her parents' home for a while. When she returned home and met up with friends from her student days, she reunited with the man who was her first love, and before she knew it, they were having an affair. Experiencing a man's kindness after so long rekindled her desire to cheat, and her playful nature became uncontrollable.
