Contrary to his innocent appearance, Kaname begins to take off his clothes!? However, Ogino, who I thought was so casual and used to women, is actually super, super, super innocent and serious!? Even the kiss is erotic. Will a serious tutor who refuses to do anything until marriage and a plump young girl who dreams of being passionately sought after and embraced like in an erotic novel be able to do something naughty?!
