This drama is perfect, simple genuine and just perfect! The acting was great throughout and all of the cast portrayed their characters especially Joo Won, I hadn't watched anything previously with him in and was really surprised at how well he pulled it off (its safe to say I'll be watching more dramas with him in). Moon Chae Won's acting I also loved, she was just so genuine that it was comfortable to watch, it was like this entire drama was real. The storylines are realistic in my opinion, they deal with issues that people with Autism experience and how they handle the positive and negative events that happen to them and around them in every day life. In particular, the workplace and a Doctors scenario too. We see how the patient cases coincide with the Doctors lives and we learn things from the cases in terms of love, family, friendships and forgiveness. As with all medical dramas I get a bit :/ with the medical terms, like i did with Medical top team, the terms they used etc just confused me so much I couldnt really focus on the plot line, but I think because Shi On's personality is so thorough and to the point he explains those terms in more basic detail combined with his unique talents so it's understandable? (I dont know maybe its just me, but i had more of an idea on whats going on than I normally do in other medical dramas) There was such a variety of characters that the drama was enjoyable to watch so it wasnt all serious business medical stuff all the time, it was a simple and genuine drama. I loved the OST, I loved the ending, I can't believe 20 episodes are over already! It didn't even feel draggy and their cliffhangers are so exhilarating it really does make you want to watch on for more!
