Story 9.5/10: As I watched the first seven minutes of the drama, I got hooked to this one. It is an unique story in the history of SBS' drama's. A love story between an alien and a human. It reminded me of Romeo and Julliet. I liked how so much details were put in the story,I won't spoil, you will know what I mean when you wacth it. Acting/Cast 9.5/10: Jeon Ji and Kim Soo were an ideal couple. I love how they matched those two. A plus were the actors cast for the teenager versions of the leadroles. I don't know how they did it, but they really looked like the adult versions. Music 7/10: I gave the music a seven because it wasn't different from other drama's.. Although the lyrics were very touching. Rewatch value 9/10: I asualy don't rewatch drama's but this one would be an acception. Because I stayed up till 4 in the morning to watch the end. Of all the drama's I watched untill now I thought my first drama would alaways be my favorite but this one equals it. Overall 9.5/10: To end my review, I really recommend this one if you like drama, love, supernatural, history, culture and life of a hallyu
