Yusuke Taguchi, a third-year high school student, passed his university entrance exams on a recommendation and was thus having some free time.Then, his homeroom teacher asks him to be a tutor for "a certain woman who is aiming to get into university", but what was waiting for Yusuke was Airi, a gal 6 years older than him. What's more, Airi-san is a Gyaru and kind of has a good vibe, but also seems to have an even more outrageous "secret"!?It's a bit radical, but somehow gentle and precious, an unprecedented romantic comedy for college entrance exams has begun!!
