I met up with my best friend for the first time in a long time. I am a free-spirited night butterfly, a refined, sheltered young lady named Yuko. We are completely different types, but we were always together in our school days. I never imagined that Yuko's husband was the man who dumped me a long time ago! More than being shocked, my Kokoro was filled with lewd expectations and jealousy. I want his Kokoro to be mine again! The dark nature of these two women, where schemes and betrayal wriggle!
