One of the best fantasy romance I've ever watch.. DEFINITELY.. I started watched this back then when one of my friend recommend this drama to me.. I don't even know who the casts was, I was just bored at the time and decide to watch anything. BUT, I ended up hooked up.. Story: the time travelling theme is not so original actually.. there's plenty of dramas with this theme. I haven't watched Rooftop Prince, but some people seems to compared these two (and from the synopsis that I read, I think it's kinda similiar).. But the flow of QIHM's story, it really carried me out.. I didn't see anything was dragged (except maybe for the last 2 episodes).. Everything was on the right line.. The story was more likely romantic than comedic (which I loved).. Acting/Cast: DEFINITELY, drama with the best chemistry within the main lead.. Yoo In Na & Ji Hyun Woo are reaaaaallllyyyy good.. Their chemistry was naturally built, and when I read that they dated for real, I am reaaalllyyy happy.. I think most of you agree, that they looks really good together.. The supporting casts are perfect.. They added plenty of comedy here and there (especially the 2012 line).. LOL.. Music: They didn't released much soundtrack, but all of them are pretty good, especially for building the atmosphere.. Rewatch Value: I usually didn't rewatch my drama, but I think I would-some day in the future-rewatch this again.. And much of you maybe would rewatch this :) Overall, again, this is one of the best romantic fantasy I've ever watched.. I adore especially the chemistry between the lead.. Their romance also pleasant to watch and makes me goes "Awww...".. One of the best romance of the year :)
