Really enjoy watching this Drama. Unpredictable, and i can say the chemistry is there. The idea of Gim Bong Do constant traveling through time is quiet interesting. Every episode is worth watching. You don't want to miss even one. I was hesitant to watch this drama because of unfamiliar lead actor. However, Ji-Hyun Woo has capture my heart with his charm. His not those typical pretty boy K-pop. He has his own way of capturing his audience. Same goes to lead actress. She's so cute despite her age. The whole plot and casting is just amazing. The music is just perfect. I recommend you to watch this. You wont regret it.
