Will keep this short and sweet. This drama is simply amazing. from the acting, writing, directing, OST - every aspect was perfect. This thriller/drama won't bore you, it will keep you to the edge of your seat. An exhillirating ride for the viewers,

Lee Joon Gi, as always, delvered his very best here. His acting was top-notch. For me, he is really one of the most remarkable actors in the industry and deserves more accolades than what he is getting now. I think when it comes to portraying complex characters, no one can beat Lee Joon Gi - those eyes, the depth of his acting, his display of different kinds of emotions, wow! just wow! Moon Chae Won also was so amazing here. I haven't seen much of her dramas, but I got drawn to her after watching this.

All the actors, the director, writer and everyone in the production truly delivered in this drama.

I hope more people gets to see this excellent drama, I assure you it's worth watching. 10/10.
