One thing I would say to anyone who is thinking of watching this drama - 'Prepare for a rollercoaster of emotions', because this drama sure made a mix of emotions. In some parts I was angry, others happy, and some more I was sad. I decided to watch this drama after reading the plot and also Park Min Young is my favourite actress. Also, I had never seen a drama with Yoo Seung Ho in and boy! Now I am going to hunt through all of his past dramas and watch them all! Story: The story wasn't written, it was crafted. And it was crafted beautifully. The staff of this drama did a fantastic job and it was everything which I had expected plus more. A large part of this drama actually gave me goosebumps. It was so beautiful and I was even on the edge of my seat in parts. It is a beautiful but sad story and it was made perfectly. The only bad thing I have to say is I wish there was slightly more romance involved but with such a crafted storyline, they managed to fit a lot of things in 20 episodes so it didn't bother me too much. Acting: What can I say about the acting in this drama? The acting of this drama was one of the best I have seen in a while. Yoo Seung Ho and Park Min Young portrayed their roles perfectly. The chemistry between them and the other characters were also amazing. But I would have to give my award to the villian/bad guy. Nam Goong Min (Nam Gyu Man). When I hear of a villian/bad guy, Nam Goong Min played everything I would expect. He gave me goosebumps and his acting was absolutely amazing (I am sorry poor laptop for me screaming at you during his scenes). I also really enjoyed a lot of the extra characters apart from those who were the leads. That's why I gave the acting 10/10. Recommend/Rewatch: I would DEFINITELY recommend this drama to anyone who loves dramas with some mystery, romance, thriller and drama. This is the perfect drama for you. Rewatch value... hm. I think I would still have to prepare myself for everything which is going to happen, even though I have already watched it! It was an amazing drama and I enjoyed every single part of it. I really do not think I was bored at any parts of this drama. So watch it! You will DEFINITELY not be disappointed! I can honestly say I loved every single part of this drama and whilst it was airing, it was the only thing that kept me going until Wednesday and Thursday nights. :)
