This has to be one of the best dramas I've seen! Everything was so consistent and even though it's a fantasy drama, it was realistic. It ticks all the boxes. Romance, Comedy, Action, Politics, Fantasy, Historical. Although there are many genres for this I feel that the writers balanced them out really well! The Casts were A-MAZING!!! The chemistry between the leads was just phenomenal. The story isnt the most unique and it isnt the best. But its strong. Throughout the whole series there was no messing about. It was straight forward and straight to the point - no fillers or anything. Some dramas have over dramatic storylines and they simply arent convincing, while this one is. It is another time travelling drama but the mechanism of time traveling in this series is very different to the ones we have seen, so you can't really compare it to Rooftop Prince because both are very very different. It's an incredible fluffy drama but not over the top. It has the more serious and heavy element that plays a major part in the series, which was balanced really well with the lovely romantic scenes. The Acting. Just WOW! Yoo In Na's first lead, and she did a REALLY REALLY good job. Ji Hyun Woo, also was amazing. Ji Hyun Woo isnt the best looking actor out there, but he shows intelligence and charisma through his character that I havent seen before and I fell for him. Just shows that looks arent everything really. Hee Jin, also is your typical ditsy lead but one thing that is unexpected is that she's actually clever and strong. She's really outgoing and bold, and this shows throughout the whole drama. She doesnt suffer from the typical i'm-oh-so-bold-but-after-episode-10-I'm-suddenly-unable-to-fend-for-myself sydrome. She can pull of the serious and heartbreaking scene extremely convincingly, before I know it, I am crying with and for her! Both of these leads are definitely going to be within my radar from now on. The chemsitry between them are so realistic and sweet. My heart has suffered many palpitations because of these two! None of the shy touching-lips-slightly kisses but full on mouth-open kisses. HOT! They are so good to watch together. If nothing peaks your interest, then these two definitely will, I gaurantee it! The rest of the casts are flawless and pulled off their characters. What more can I say? A lot but I'm not going to bore you with how much I love Yoo In Na and Ji Hyun Woo right now :D! Be warned, you cannot stop smiling when watching this. The music compliments the acting and the story really well and relate to the theme of the series. I have downloaded the full OST and I will enjoy it because it was one of the reasons that got me hooked from episode one. I'm buying the DVD when it comes out so I will definitely rewatch this :) Although some things aren't explained it's pretty much up to your own imagination to figure it out. And most probably you will be right. If you are looking for a romantic comedy with strong non stereotypical leads this is definitely the one. For me it was perfect in every way and I really cannot fault anything.
