Dowon is a near-chaebol background, handsome looks, and a gentle personality. A seemingly perfect man who has it all, he has one bad habit: [He only dates women who are already taken.] An ordinary appearance, completely average, and a pitiful woman. At a reunion drinking party, Dowon reunites after six years with a college junior who had dared to push him away simply because she had a boyfriend. As someone who isn't satisfied until he makes his prey entirely his own, Dowon finally gets a chance to spend a single night with the junior, only to be hit with an absurd remark about wanting to peg him instead. Trying to persuade her fails, so Dowon eventually changes his plan: pretending to go along with it, he decides to sweet-talk her and play along for now...
