I know I have not watched yet a lot of kdramas that ppl loved this year (for example the good bad mother etc) but this for me was the BEST kdrama of the year. I loved it so much that I had to write a review even if I rarely do so.
I just found out this was a remake of a chinese drama, I'm not sure if I'll watch that one, just cause I'm curious but all I can say is that no matter that one, this drama was made very good.

I won't make spoiler in this review but I will tell you its a CONFUSING drama, at least for the first 8th episodes. In number 8 you'll start putting most of the pieces together.
On one side it was such frustrating not understanding ANYTHING of what was going on and where all was going to go til the very end but that was what made this drama beautiful.

The acting of Ahn Seop was really amazing on this drama and also all the other actors were very good even if his performance was my fav (if you watched the drama you'll get why I say so).

Only thing i can say is that for me the rewatch value of this i very low. I've rewatched true beauty or Land crushing so many times but this... I'm not even sure I can watch it a second time because when you know and find out everything than its done. You can love or hate the story they invented but when you know it, in my opinion, rewatching it its a bit pointelss since the all point of this drama is that you wanna so desperately to find out whats happening .
