Things are developing!

I like the way Hyun Woo is making his revenge but I can't see find a reason to why is he shutting nurse Yun down, I know that he doesn't want to get her involved but I want a romantic plot too!
On the other hand, I am glad to see Ah Ran and Joo Seung fighting because of Hyun Woo, that's making things more exciting. Another thing that I am excited about is the appearance of Jung Sang Mo's sister, I am sure that she will help Hyun Woo in his revenge since they share the same goal.
