Bad Guys - (previously watched) fun and intense drama about a bunch of psychopaths running around and catching other psychopaths; marathonable
Awl - (currently watching) realistic drama about labor unions and how brutal the work force is; slow but addictive

Rooftop Prince - Not even a kdrama fan but this caught my interest
Reverse. It's on my PTW list too and I'm really curious about it.
"Age of Youth" - I never expected to like it as much as I did + a new season is airing this month!
