Nice ending!

If Hyun Woo's identity is going to be exposed then I am sure it will be because of nurse Yoon, she can be really stupid sometimes; I never liked naive characters!
As for Ah Ran, I think she's being too reckless, for someone who did everything including murder to commit his revenge, I find her too weak now, you can't let your guards down when you didn't accomplish your goals yet but from now on, I can see that she will fall for Hyun Woo completely. Let's wait and see...
