Yukino Miyazawa is the perfect model student. Pretty, kind, good at sports, always at the top of her class. But she's not all she seems. It's all an act of deception; she is really the self-confessed "queen of vanity," and her only goal in life is winning the praise and admiration of everyone around her. When she enters high school, she finally meets her match: Soichiro Arima, a handsome, athletic, popular, and very intelligent young boy. Ever since he stole the top seat in the class from her, Yukino has hated him, and has been plotting on how to take back her former place as the object of all other students' admiration. What she wasn't expecting, however, was that Soichiro, the very boy she hated, would confess his love for her. She also didn't expect that he would find out about her deception - and use it to blackmail her! Together, they discover that they have more in common than they knew, and they promise each other that they'll stop pretending to be perfect, and just be their true selves.
