I don't know how I missed it. And I tell you if you're into suspense, some drama, detective story and a very good tangled storyline you have no excuse not to watch it. It's just so good. And not good because of one character or good acting. It's a complex of factors that make this drama memorable. Firstly let me say that this drama is a good example of detective story. So the storyline is a perfection. It's difficult and I was amazed how the story remained the same, there was only one major problem which was enriched by other stories which at the same time make the final choice fatal. So you won't be bored by the storyline, that's for sure. Then acting. It was really good too. So the big plus from me. Although I liked Daniel so much better. G.O. by the way was magnificent. I didn't know that he is such a good actor. And there were a lot of attractive nerds if you catch my drift ^^ The absolute advantage is the absence of widespread love story. However there are three couples taking shape. And that was kind of adorable. Music was modern and good. But I give 10 for the Phantom of the Opera. It was nerve wracking here. And finally I must say about my favourite character. I just fell in love with Jo Hyun Min. Some people may say that he was an ordinary villain. Oh no this time it was different. And the finale, Oh My it was unforgettable for me. Seriously he made me think. The revenge... what is its cost? The love? The alliance? Uhm Ki Joon did extremely well. And its worth watching just for him. But this drama is much more than that. And if you have free time and want to spend it in puzzling over the script this drama will be just for you. I liked it a lot! 10!
