I rewatch it a month ago...
I enjoyed it more because i knew what was coming.
The story is interesting, the separated lovers and the endlessly effort to reunite. I didn't like the plolitics, wish it has more "hospital" time, more interesting ways of showing the awesome skills of Park Hoon.

A little long to me, could be cut to 10 or 12 episodes.

I think the end is ok, a little rushed for me.
I don't understand Park Hoon decision of living in a remote place and a remote hospital Is he going to waste his ans Hang Seung Hee skills?

I was completely addicted in the first 8 to 10 episodes! But after that, they did dragged a little: don't understand the 16 episodes formula. Few dramas deserve so many episodes and most of them tend to drag the story.

Overall, this could be a master piece but it fail to deliver...

But, if you like beautiful and true love, a plot with lots of twists and mistery, great moments of suspense, excitement, specially in the O.R., them please watch it!
