The thing I most liked about this drama is that it's so refreshing. It has no over-the-top plot twist. Just a story of five friends and their journey in life. The story is so peaceful but not boring. The actors did their job phenomenally. This is one of those dramas that you can watch over and over again, and never get bored. Also thank god there is no villain in this drama. I think this is the only hospital drama, I have watched, where there is no power struggle. Just the realistic lives of the doctors, great friendships, and even the friendship between Jeong Ro Sa and Ju Jong Su were so good. This drama teaches the value of relationships and how to maintain them. Seriously hoping for a third season with the original cast.
