Single 33-year-old Go Byeong Hee works as a reporter for a sex magazine. She wants more romance and a more respectable life but isn't sure how to get it. 24-year-old Park Chul Su, mechanic and world traveller, is the younger brother of Byeong Hee's best friend. He's free-spirited and not concerned with what the world thinks. One night, the two old family friends get drunk and wake up in bed together. Go Byeong Hee wants to forget it ever happened, especially since a good marriage prospect has just made an appearance. Unfortunately for her, Chul Su has other ideas.
