Started off watching this drama and it was fast moving..plenty of twists to get you thinking..the acting was superb and the storyline it seems excellent but there was that much going on that I got confused part way through.I love meatier Korean dramas and for someone who really understood the story and could differentiate who was who this drama had everything.I decided to stay till the end and I was even more confused.This is
only my opinion and it doesn't take away how excellent it was for other viewers..
