I'm a fan of mystery and mind blowing dramas so I watched this. I thought I already know the culprit after watching the first five episodes so I almost stop, GOOD thing is I continue to watch it cause after every episode you will be confused. The story is twisted until the end. Even if you watched every part and you already made up your mind on who the real culprit is another thing will happen so don't judge quickly.
I also like the fact on how they connect each story to the main problem. And the fact that the lead man is Yoo Seung ho is great! He never disappoint me in his actings. And of course, the support roles also did a great job! ???
