One drunken night, the wrong bed, and the worst roommate you could have possibly chosen. And now, what the hell are you supposed to do when you're pregnant with HIS child?

Lee Ji-won has everything money can buy: a wealthy family, a life of luxury, and an absolutely unjustified amount of self-confidence. He's a spoiled, arrogant rich kid, so unbearably obnoxious that sometimes you wonder how the hell you've managed to survive living under the same roof as him.

But one night, things got out of hand. Between drinks, blurry memories, and a series of COMPLETELY STUPID decisions, you ended up waking up in his bed. Congratulations! You're one month pregnant!
