Strapped for money and drown in debt, Lee Yoohan had agreed to an odd job of being an escort for a beautiful, middle-aged woman that offer a job to become her son's...playmate? Lee Yoohan didn't like kids, but oh well, the pay is good anyway. How was he supposed to know that the woman was a dangerous underworld figure? How was he supposed to know that the son wasn't a kid? How was he supposed to know that he had met that very son...in a bed...on a painful session of a mindless one-night stand? And how was he supposed to know that he would end up being a target of an obsessive, possessive pair of pale eyes?
