To say that Mona Kawai is cute is an understatement; she's stunning in every way, and she knows it. At school, he is adored by both boys and girls, and he graciously accepts it all as a natural reaction to his irresistible charm. That is, until he meets Medaka Kuroiwa, a boy who seems immune to his overwhelming charisma. She tried hard to talk to him and even increased her cuteness, but no matter what she tried, Mona couldn't wipe the frown off Kuroiwa's face. Cornered, Mona is forced to use the deadliest weapon in her arsenal: her physical attractiveness. Such drastic measures would have made other boys foam at their mouths, but Kuroiwa remained unfazed by his efforts. Little does Mona know that the only reason Kuroiwa barely gives in to her charms is because he is training to become a monk and thus tries his best not to be restrained by worldly pleasures. While Mona tries her best to charm Kuroiwa, she fails to realize that Kuroiwa's unintentional polite gesture could actually make her fall in love with him.
