I totally love this drama, the story is so good and original in its realism, without the unnecessary drama of some other series. Completely love the medical stories, albeit they were sometime heartbreaking.

Story:
It was a great story focused on the life of 5 doctor friends, who've been there for each other so much that they are essentially family to each other. I loved the interactions they had when together and how each one has their own style when dealing with patients and other medical professionals and staff. The medical stories were great, so well explained that a non-medical professional could easily follow it and so greatly immersed in the overall plot that was so well planned.

Now, regarding the love stories, it was fascinating how they were developed, from the get go we know Dr. Jang Gyeo Wool has a big crush on one of the big 5 (Dr. Ahn Jung Won), who is less than impressed with her people and empathy skills. She then proceeds to slowly change in the course of this first season and continue to grow as a doctor. On the other hand, we have Dr. Chae Song Hwa, which I will admit, at first I thought that Dr. Kim Jun Wan had a thing for her, but as the show keeps developing, we can see he always saw her as a friend, unlike the other 2 guys of the group, Dr. Lee Ik Jun and Dr. Yang Suk Hyung. In this case Song Hwa had already rejected Suk Hyung, and Ik Jun to not hurt his friend further didn't confess, but now as he divorces his cheating ex wife, finds himself falling again for Song Hwa, and now he cannot avoid confessing. It turns out that she already has a someone crushing on her, her resident Dr Ahn Chi Hong, whom she is at first unaware of his feelings and later on has to deal with him. I find very interesting how the relationship of Jun Wan and Lee Ik Sun will develop with her out of the country for years on her master's degree in the UK, hopefully they will not break up. I am also eating too see what Suk Hyung ex-wife wants with him and why he says he feels apologetic towards her, I honestly hope that at the end Dr. Chu Min Ha finds someone deserving of her, I think she is a great character that deserves someone who appreciates what she can offer. As anyone can see the relationships are complicated, but they get very well developed and one can totally see how they go forward. I am waiting impatiently for the second season.

Acting/Cast:
Great acting from all the main and secondary cast, even the guest actors were great. All the dramatic scenes were very well developed and managed to transmit the feelings that they must. I think that when a drama can make you cry watching it, it is a great one and a sign of amazing acting ability by the actors. They all show different feelings and do not remain static (like Jun Wan being tsundere all the time, he sometimes acts cute and silly), this shows amazing acting ability and allows the audience to see how far the actors can go.

Music:
So pretty and the message that they convey great for the scenes and episodes where they are used. The Ost consists of a lot of different songs, which I realize are oldies in South Korea, but are so good to the ear as they are not the typical K-pop songs we are used to now.

Rewatch Value:
Very High, I continue watching it because I love it so much.
