My favorite k-drama. I said it.

The plot caught me so bad.
But this show wouldn't be so good without this amazing cast.
I had a love at first sight for Doctor's son. The actor was made for this character. He was so mysterious, so dark and charismatic. Even kneeling, he kept his dignity.
The main actress wasn't bad and was pretty.
But GOD, the second leads were ALL outstanding. I feel like they completely played with my heart during the whole show. I hated them. Loved them. Wished them to die. Wished them to live. They tortured me.

There was not enough romance and felt so frustrated. But well, if there was more romance, the show wouldn't be so dramatic and dark. So it is forgiven.

The ending got me as well. I hated it but, at the same time, liked it. There was, honestly, no other ending possible.
