A family almost as wealthy as a chaebol, striking good looks, and a gentlemanly personality. Dowon seems like the perfect man who has it all, but he has one terrible habit. He only dates women who already have boyfriends. An ordinary-looking woman. Nothing special, nothing different from anyone else. Just a completely unimpressive girl. Six years later, at a college reunion, Dowon runs into a former university junior who once had the audacity to reject him simply because she already had a boyfriend. Once Dowon sets his sights on his prey, he won't be satisfied until he's made it his. He finally manages to get a chance to spend the night with her, only to hear something utterly absurd: she wants to be the one penetrating him. Dowon tries to persuade her otherwise, but when she refuses to give in, he eventually changes his strategy. For now, he'll pretend to go along with her wishes and sweet-talk her into doing things his way...
