In class, she's a sort of zoned-out girl, and he's the year one class' most perfect, good-looking guy. But the two of them have a secret, and their extraordinary "love experience" will start now! Himuro Yukina, known as the "Absolute Zero Snow-woman" is a cold and observant girl. In addition, she is actually a popular cell phone novelist who goes by the name of Yupina. Sadly, with no other human contact than her cousin, Yukina is unable to express more romance in her novels. Kitami Shigure, your so-called "typical bishounen", who is really a womanizer, has fallen into Yukina's trap when she blackmails him, and Shigure ends up doing Yukina's ''missions of love''. As this continue, will these ''missions'' be a opportunity for them to fall in love?
