First of all, I wanted to watch it because I was curious with Jung Yong Hwa's acting comeback after military enlistment, I have watched his 2 previous dramas and I found he was always acted as a cool and calm guy. Then surprisingly in this drama, his acting improvement is so awesome. He can act in various emotions when he is possessed. No worry about Jang Nara, she is veteran and she nails her character. Badass and smart. Their chemistry is so cute hahaha I don't expect too much, but after watching first episode, I knew that their pairing is shipable on screen. :D
