Park Eun-jin is a loudmouthed thirty-year-old with an abysmal track record in romantic relationships. Freewheeling and adventurous, she is also irresponsible and reckless, pushing away the timid and the cautious, yet always falling for the romantic dreams of the love-conquers-minor-details-like-my-lover’s-married-status variety. After a spectacular break-up with a co-worker, Eun-jin shares a cab ride with Kim Hyeon-seok, a nerdish, awkward young man. Against all odds, they begin a courtship and eventually decide to get married. One night, however, Eun-jin finds a suspicious text message sent to her paramour’s smartphone. Angered, she enlists the help of her female cop friend So-young and her doofus ex-marine brother Eun-gyul to get to the bottom of what she suspects is Hyeon-seok’s two-timing affair. What she finds out, however, is something else altogether.

Lee Yoo-rim is a high school English teacher. He’s cute, clever… and shameless. Choi Hong is a student teacher, even though she is one year older than Yu-rim. She’s cynical and always plays hard-to-get when a man shows interest in her. While going out for drinks one night, Yu-rim suddenly tells Hong that he wants to have sex with her. Hong is hardly impressed. And so begins a battle of will and wits, both between each other and within themselves, as both Yu-rim and Hong are unsure of what each other wants and what they want themselves. Dating and desire mix explosively. What is the point of this strange relationship? What is the object of their desire?
