I started watching this drama when I accidentally saw the trailer on YouTube and saw that Yoon Shi Yoon was the main lead. I only knew about him in 2 days and 1 night so I wanted to see how he acts in a drama. When I started with the first episode, the first thought I had was that the story was interesting, in a way that I wanted to know how the next part would unfold. I had the same feeling over the next few episodes but as it got around ep 13 and beyond, it felt like the story was going in circles. Personally I thought they were better off at making it a 16 ep drama rather than a 20 ep. If they did, the story wouldn't feel draggy and I wouldn't loose interest halfway through the series. Be that as it may, the characters of the main leads were well played. I like how Kim Sae Ron acted her role as Yeon Hee. She had a strong hold of her character and she was consistent throughout the episodes. For someone so young to be able to do this makes me excited for her other dramas( hopefully she would also lead in it). As for Yoon Shi Yoon, he was good but he lacks the aura of a main lead. He has it but there were some parts where I question him being the lead. He lacks that stance that male lead characters have. But even if I say that, he was still able to convey Heo Jun's inner turmoil well. As for the other characters, I can say that they, especially the characters of Hong Joo, Queen Shim and Choi Hyun Soo were exemplary actors. They played their roles really well, although Hyun Soo had some parts that were not written well (like the part where he constantly hides the truth from everyone making things complicated). The music was awesome, I like the selection they made on this drama. I wouldn't rewatch this drama. Overall, it has an interesting plot that needed a little twerk, with excellent and good actors, complemented with the right cinematography and a smart selection of music to mirror the scenes in the drama.
