Jang Hyuk and Jang Nara had really good chemistry together. I loved how playful they were with each other. I felt that his acting was, unfortunately, over the top a lot of times, and that laugh, ugh! I also either wanted to go at his hair with a pair of clippers or loan him a barrette, his hair was ridiculous. My favorite scene with him was in ep 18 during the press conference. He was understated and you could really see his fear and hope and love shining through in his acting without all the antics. I did NOT like the drugging aspect of the show, and there was an awful long time for them to be apart, after the obligatory three-year separation. When he was pretending to be someone else and they were texting one another, that was very cleverly done, and gave us more opportunity to see them together. I also loved the storyline of him taking the female lead's mom as his mom. Very touching. Choi Jin Hyuk as the second male lead was excellent, and his deep voice...yum. The ending was very cute and you get to see a wedding and what happens in their lives after that, which I always like after spending all this time watching a show
