unbelievable, this is my most addective drama, there are a lot of twist, I can't this much strong female, deabak..
story line is so boom boom.
music and songs are so good too(already added in my list
acting
for acting I give 10 Stars (even they deserve more stars) every single person did a great job.
if you love action then don't waste your time here.
even the first episode will make you obsessed with this series..
re-watch value is 10 to 10 I will surely re watch it. but everyone have different taste so maybe this drama will be little disturbing for them who don't like violence.

I won't give any spoiler but gangjae deserve that
