Cafe manager Arata is almost 30, and he can't get girls because he's just too big! But, everything changes when he meets Shinya, a serious and way-too-innocent college-student who also happens to be a rare form of succubus... a male one. Shinya feeds off of a certain bodily fluid that Arata finds himself all too happy to provide. The sheer contrast between Shinya when he's "feeding" and his usual good-boy self is just irresistible in this ultra-fluffy, sweet, sultry romantic comedy!
