I want a boyfriend! But there's no chance of finding one at an all-girls school... Hina, who started working part-time with ulterior motives, meets an extremely handsome university student, Kataya Zen. Hina is instantly attracted to Zen, but it turns out that Zen is a man who is very careless with women. "Don't fall in love with me, okay?" he says... but it's already too late! A love battle begins between a woman who is a total novice in love and a playboy who she should never fall in love with, with no hope of winning!
