I have only words of admiration to Gong Yoo and Seo Hyun Jin who really portrayed Han Jeong Won and No In Ji well. ++ to their amazing chemistry. Their chemistry is chemistrying.

Also, I have to mention Jung Yun Ha. She's an amazing one. She annoyed the hell out of me proving that she perfomed Lee So Yeon incredibly.

However, the mystery isn't giving that mystery. As said earlier, this series could survive without it. Side stories also shouldn't have been introduced if they weren't concluded properly. I do do love the soundtrack tough. It is wonderful.
