"You know why you, who can't work, are here, right?" The secret of Secretary Hina Yui, who will never be fired no matter how many mistakes she makes... is that she's the president's obedient pet, hired as a sex disposal officer. She's a 0 as a secretary, but a 200 as a mistress. She's a talented person in a way, able to do it anytime, anywhere. Making up for her usual failures with the best service sex.
