This is a drama that you'll either love or at the very least enjoy. While many will rate this drama with a score of 9-10, I'm going to give it an overall grade of 8. (To be fair, I'm a little picky and never rate a drama with a 10.) Story The first two episodes of this drama really grabbed my attention. Just the pilot episode itself was emotional, exciting, and funny without feeling forceful at all. The most rewarding aspect of this drama is the character development and interactions; it was very convincing despite the major changes in most characters. However, with that said, I felt there were moments of fillers. Also, despite being a medical drama, I would say this focused more on their relationships/personal situations, such that even for surgeries, it was more about whether to do the surgery or not (or that's how I felt about it) Acting/Cast The acting and cast were excellent. Everyone did a good job. Particularly, Park Shi On (played by Joo Won) did an awesome job in portraying the role of an autistic; I think he'll be highly recognized for it. Doctor Cha (played by Moon Chae Won) Also did a good job. Moon Chae Won is actually one of my favorite Korean actresses, but I was a little afraid based on the teaser trailer that she'll play a passive character. However, I was wrong and really enjoyed her character here as well. Their chemistry was also impressively convincing. Music I'm not much of a music expert, so I don't really have much input. All I would say is that it felt suitable, but not great enough for me to want to listen to the ost on its own. Re-watch Value It's definitely re-watchable. I rated 8 because I cannot ignore the fact that I would skip a good amount of parts. Although many dramas do have moments of filler as well, I still feel that I have to include that to the equation.
