Sachika moved from Osaka to Tokyo when her husband became independent. Sachika had always dreamed of living in Tokyo, but in reality she had no friends there, and said she now felt more lonely than during her time in Osaka. Her husband was busy with work, and her feelings of loneliness grew stronger with each passing day. One day, her husband was away on a business trip and Sachka was alone, so she went out to eat alone. Afterwards, she wanders into a bar and meets a man (Jun). From that day on, she was driven by the desire to have an affair, and began having affairs in search of female pleasure.
