I've seen the name of this drama mentioned quite a few times at "Must watch Series" but never watched it cos of the vague descriptions. Accidentally I clicked the first episode on Netflix and I'm really glad that I did. Else I would have missed this masterpiece. Let's first talk about the actors. Kudos the entire cast and specifically the male lead Jo In Sung. At the end of this drama, he became one of my favorite actors. What a charming personality he has. No one could have give this much justice to the role than him. The next favorite would be Do Kyung Soo. As a troubled yet bright teenager, he for sure makes us empathetic towards him. Lee Kwang Soo as Tourette Syndrome patient definitely stole the show. I was never a fan of Gong Hyo Jin but this drama totally changed my view. The chemistry between Gong Hyo Jin and Jo In Sung is undeniable and the OSTs helped elevate it to greater heights. Not to forget the bromance between Sung Dong Il, Jo In Sung and Kwang Soo. May be with Gong Hyo Jin too. This drama for sure will leave a mark for a while. If you have not yet watched, do start it right now!
