I don't even know where to start... it's been such a LONG time since I've seen a drama as amazing as this one! And I know it really irritates people when reviews are being made when the dramas aren't finish airing yet, but I'm sorry. I can't help it. This drama is superb. Story-10 , Definitely one of the best story lines in the dramas that I've watched. It made me laugh, jump up for joy, frustrated at times, and even get mad at the leads sometimes! Very unpredictable! I expected for things to happen, but it twisted and went the other way around. I usually don't like romance between an older woman and a younger guy, but it's exceptional here! The story definitely kept me at the edge of my seat throughout the whole episodes! Acting/Cast-9, The actors portrayed their characters very well. Lee Bo Young annoyed me a bit at first, but she turned out to be really good. Lee Jong Suk is just simply amazing. This is my first drama with him in it, and I fell in love at first sight! He is spectacular for a 23 year old. Yoon Sang Hyun is really good too... but I didn't really payed much attention to him in here xD Plus, the chemistry between Jong Suk & Bo Young is incredible! Music- 8, the music's pretty good. Some really great OST's there! Rewatch value- 9, I watched this 3 times already and never got bored once! xD
