When you've dated the baddest of the bad, you'd feel so done. That's just what Yoo Areum felt as she broke up with her now ex-boyfriend, Kim Himchan. He cheated, lied and betrayed her and she's sworn never to make the same mistake of dating another guy just like him.

The problem is, she's got a huge thing for bad boys.

What, or rather who could possibly change her mind?
