Kim Yooyoung is sick of playing the nice, boring lawyer and daughter. So when her overbearing mother books her a hotel room the night before an arranged blind date, she steps out of character and spends the night with a seductive stranger from the hotel bar. Only this stranger turns out to be none other than Cha Jihoon, her blind date and the hotel's high-class owner! Yooyoung will do anything to keep their "bad deed" a secret... but can she really marry her first one-night stand? (Source: Tapas Media)
