Ichijou Jun is a high-school student. However, he is a loner and even on lunch break the only thing he does is studying. As a result of great effort, his test ranking rose and while he was satisfied with his loner life, – Hi-hi-hi… virg*n, teach me agaain♪ – Shut up, b*tch. Let’s finish it quick today, OK? – Yay! One day, it was decided that he will help blonde gyaru Tachibana Karen, central figure of the class, with her studies. Loner during lunch break, tête-à-tête studying after school… So continues the double life. Tsundere-like, but good at taking care of people Ichijou-kun. A bit mischievous Tachibana-san with an innocent smile. With this and that happening, the two get along so well that others cringe.
