I have to say, this is my favorite drama up-till now. I actually do not watch action drama's, only romance, but this one. Genius. Pure genius. The story is so addictive. It is really well written, every character gets it's own time to shine and they are very well developed. The love-part has not yet been developed very well, so for people who want the romance, patience. I am not going to spoil anything here because you should watch it yourself. You get emotionally sucked into the plot and even-though you might hate a character (or love one) they develop so well that your opinion changes very fast. The fact that it is set in '30 Korea when Japan was invading makes it so different from other drama's, which is very refreshing. I have to scream it. JOO WON IS AMAZING. He is such a great actor. I mean, this is the best acting I have ever seen. It is so incredibly good. And not just him, (eventhough he is like, magnificent) but everyone is great. It is really well cast. I immediatly fell in love with the OST Goodbye day. It is such a beautiful song, and I started screaming when I found out it is by Ulala Session. It matches the whole feel of the drama perfectly and is a song you would listen when not watch the drama. The rest of the music also fits in perfectly. I have to say, this is something you have to like. If you don't like the first ep, then don't continue because it will stay the same. It is complete different from what I have watched so far and this is my taste, but my taste isn't everyone's. So think it through, because it is very addictive (watched 10 eps in one go). Because it's only at 10 eps I can not say anything very particular about the rewatch value because could take a different turn in the later eps, but what I have seen so far, I know I will definitively watch it again. Overall I love it, it is my favorite. It is so different, and there were like 2 scenes where Joo Won was singing this old-fashioned fancy song in a club and he broke out into dance. That was just awesome. Just awesome. It's because of his great acting I continued watching. I highly recommend this drama.
