Aoi (who is a boy, not a girl) has always admired Arina – the president of the school's literature club. Next year, when Arina graduates, the club might be disbanded due to having too few members. But luckily, both of them got to participate in a national spring literature competition. When we arrived at the hotel near the competition venue, we found out that the hotel staff mistook my name for a girl, so they only booked us one room! And a virgin boy like me shares a room with the beautiful yet extremely charming president!!! And then she taught me about sex and much more!!!
