STORY: I've liked that this drama made me cry, laugh, love, angry and sad. My emotions was all over the place watching this drama. I don't know what to feel especially when it was nearing it's end, I was an emotional wreck. Anyways, the story overall was great! I always am partial to korean drama's that has a supernatural/fantasy plot so my opinion might be a little bit bias.
ACTING/CAST: Shin Hye Sun - her acting was excellent, I liked her in Still 17 that was one of the reason I watched this show too. Kim Myung Soo - Well I am an INSPIRIT! So whatever drama they are going to come out I make sure I watched no matter what it is! Though I must confess Myung Soo-oppa's acting is very good, he is getting better and better at it. Keep up the good work!
MUSIC: Oh gosh, you guys had no idea but I had Oh my angel by Chai on repeat! The other OST's are very good too!
REWATCH VALUE: I will most definitely rewatch this drama!
OVERALL: 9/10 Great Story, great OST and Great CAST!
