Ookami Shoujo to Kuro Ouji

Erika tried to pretend that she have a boyfriend just to fit in with her new friends but when they suspected her that she's lying she took a picture of a guy on the street as an evidence, however without knowing that this guy is studying at the same school. She begged for him to pretend to be his boyfriend and thought that he was a kind prince because he agreed to it, suddenly he asked her to turn around thrice and say "woof!". As a return he wants her to be his pet. :) The guy's name is "Kyouya" ;) Pretty cute huh!? And this guy is a complete sadist.
