Kouta is the school's idol loved by all - his teacher, and his fellow students. At least the one teacher and three students we see. Who are all girls. And they don't actually "love" him all that much, they just want to fuck his brains out.
Based on the hentai game by Tinker Bell. Shio Atsushi is a professor who will provide home class to two daughters of different families : Arisa and Maya. But it seems this won`t be only educationnal purpose since the two girls show interest to that man.
