Shigure Kitami is the student body president and the most popular guy in school. His father is the director of a big hospital. He owns a student notebook that lists every girl in his 9th grade class and puts checks next to each girl that confesses their love to him and also writes the method they used to confess to him and he turns them down each and every time. One day he drops this notebook and Yukina Himuro, the heroine of the story, finds it, and uses it to blackmail him into teaching her about love to help her write her cell phone novel. In the novel, he is the Count. Yukina uses Shigure by giving him "missions", like holding her hand, embracing her, and step-by-step, a relationship starts. Shigure hates the missions given to him by Yukina in the beginning, and tells her that he'd never fall in love with her, but several times he attempts to kiss her because he does not enjoy watching Akira Shimotsuki, Yukina's cousin, steal her away. Their missions are interrupted by the sudden appearance of Mami Mizuno, Shigure's childhoood friend who Shigure seems to be close to. In the first few chapters, Shigure never showed much interest in Yukina but jealous reactions to Akira and Yukina's relationship indicate that he really does like her and wants to be romantically involved with her.
