Saitou Haruka's alias is Sayuri, a naive girl who attends Internet chat cafés. In reality, she is a "Sakura", a girl who attends these Internet cafés, cheating off of ignorant men and their affections towards her by re-selling the jewelry and clothes they give to her for money. She wasn't like this a few years ago, and she blames her shameful father for it. She swore that she would never become like him, pathetic, helpless, poor and always begging for forgiveness whenever he makes a mistake. Suddenly, one day, while planning for her next date as Sayuri, she bumps into Kouki, who she finds has everything she wants in a man: Wealth, ambition and good looks.
