Our hero is a guy who, because of his father's move abroad, decides to start an independent life and moves to a new place, not far from his aunt's house.
Soon it turns out that the aunt has taken care in advance about what school our hero will continue his education in his new place. And everything seems to be great...
But the only thing that learns in this school are only girls, well, and on top of that, the director of this school, none other than our favorite aunt ...
Maybe it's just Auntie's bad joke. Or in this way, at the expense of our hero, she wants to accustom young girls to male society?
It seems that soon we will find out, and in the meantime, the hero will have to learn in very difficult conditions ...
But what kind of learning can there be? When around, wherever you look, cute and pretty girls, showing not a little interest in the only guy in their community ...
Well, the hero and heroines of “Koikatsu Department” are already eager to get acquainted.... Let's not keep them waiting!
