Yukina Himuro has always been feared by other students in her classes because of her sharp eyes and cold skin temperature. She is also secretly a cell phone novelist by the name of "Yupina", whose cell phone novel is very popular, that is until Yukina hears from two other girls that her novels are getting bored due to the lack of "romance". Worried about her novel, Yukina doesn't know what to do until the famous student council president Shigure Kitami comes along and accidentally drops his student handbook. Yukina picks it up to give back to him, before she sees what is inside; she finds out that he writes the names of the girls in his classes that have confessed their love for him. She then has the idea to blackmail him and he has to "love act" with her to get it back (but she only wants it for her novel). She has a fear of being seen directly without her glasses; a fear in which Shigure Kitami uses once, leaving Yukina alone and allowing her to be surrounded by other girls and frightening her. Throughout the manga, Yukina develops feelings for both Shigure and her cousin, Akira. Being a novice at love, she is emotionally confused and can't decide between them. She ends up 'unintentionally' teasing and leading both boys on, and her cellphone novel is used as an excuse by the mangaka for Yukina to romantically interact with both Akira and Shigure.
