I so enjoyed this drama and had a hard time breaking away after hours of watching. The actor Jung Woo Sung did such an excellent performance. It must have been very difficult to not speak a word through out and still perform and convey the message thru his acting. Shin Hyun Been also did such a great job. The storyline definitely gives an insight on what a deaf person goes thru. There were things in the drama that I never put a thought to it when I run into a deaf person. It is heartbreaking to see what the character, Cha Jin Woo went thru starting at such a young age. Puts a totally different awareness when someone is deaf. Thanks to the writer for putting out such a great story. On another note, I love seeing the "behind the scenes" for dramas/movies because it gives me a realistic view on the actors and the extremely hard work that goes into producing such excellent entertainment. Thanks to the actors and all that worked on this project. I am a huge fan of Kdramas and watch them daily.
