A MUST WATCH FOR ANY SEO KANG JUN'S FAN AND/OR THRILLER's FANS !

The acting, the rewatch value, the OST were the strongest points.

The OST were pure gem, they fits all perfectly the different sides of this mystery thriller sad dramaatic epic action drama. If you want a preview of this drama then you can simply listen to the OST and you will get a glimpse of what the drama is about perfectly well.

The ACTING is fantastic ! One of the best acting I have ever seen. Seo Kang Jun delivered on this one like there is no better drama out here at this level of acting, from my poinf of view or if there is please tell me. I am curious.

The rewatch value is HIGH HIGH and only HIGH I have watched this drama at least three times.

The story is great, though in the middle was a little bit annoying but it was made on purpose for the overall story, at the end you understand why you went through annoying parts of the story!
