I just finished this drama. I wish I could say I loved it; after all, I love the main leads and many of the supporting cast. However, it was so SLOW GOING. It became a chore to watch this. 20 episodes are too many; could've done this with 16, at the least. And, then, after all that, the ending seemed rushed.
I finished this yesterday and I feel a little lost today. Best drama I've seen in a while. I think the last Korean drama I liked this much was Healer. Great cast, excellent acting, wonderful storyline, stunning cinematography.
