Ryona has been married for two years. She was supposed to be living a happy life with a man she met at work, but... She ends up suffering from her husband's verbal abuse. Initially, she wanted to support her husband, who was emotionally worn down by work stress and other factors, Unable to bear the increasingly severe emotional abuse any longer, I decided to return to my parents' home for a short while. Upon returning to her parents' home and meeting up with friends from her student days, she unexpectedly reunites with the man who was her first love, and before she knows it, they are having an affair. Experiencing a man's kindness after so long rekindled my desire to cheat, and I couldn't stop myself from being playful.
