I lately find myself watching the Official OST MVs before deciding to watch a drama and it never fails to set the tone for my expectations. This drama is special to me because it revolves around a son's Love for his father and vice versa. No episode was dull for me, it always kept me on edge. And it shows the various father and son dynamics. There is one character in the drama that was so twisted but at the same time so innocent. The drama also did great interjecting some comic relief here and there perfectly, and warm scenes were sincerely warm and happy. Acting and Casting was AWESOME. All the actors made me their instant fan. Crying scenes made me cry buckets as well. It can also get frustrating but definitely rewarding. I wondered why I didn't watch this when it aired before.
