If you haven't watched this you need to phenomenal!!! Has a couple of my favorite actors in it so of course I had to check it out and it was well worth the watch I finished it in a day and a half! ? If you're on the fence about it at all just watch it! The storyline was awesome the edge of your seat thriller part of it was amazing I am in the US I never thought I would be watching k-dramas or any shows like this they're not usually my typical and I'm very into them now this has changed my perspective
