If you are hesitating to watch this drama or not, you should remove all doubts. This drama is good~ Story itself is very touching. It made me think about troubles which appear when you're different and how hard is to accept someone who is not like you. It is very easy to say but so hard to do. To try to understand another person and not to blame, not to hate. And characters in this drama have come such a long way, every one of them and it was so amazig watching their change. And I'm not sure that I' m strong enough like Do Han or Yoon Suh. And this is why this drama is so special. It makes me think, it makes me emrace the world as it is and to see beauty in it. Furthermore there were a lot of touching supporting roles. As for acting. It was INCREDIBLE! First of all Park Shi On. I don't have words to describe how good he was. He was just perfect. He played so well that there wasn't even a thought that he is normal human being like all of us. It seemed that he was a special caring soul. I'm just so grateful that he was serious about this role. But other actors were also magnificent. All of them wew such a great team. I loved the complexity of characters, their richness. Although this drama may seem a little boring and slow. But because of the fact that it shows human relationships and human nature it is right. It is a very good example how to make a very good drama. Watch it. I'm sure you won't regret it, because you can find something that you'll like. Such good doctors in a such good drama.
