To be honest, I don't watch Korean dramas that often. But when/if I do, I get pretty suckered into watching them (with the exception of She's So Lovable... for some reason, I couldn't bring myself to finish it because the premise of the story just felt so... wrong?).
This time it's The Producers.
**update: I finished watching all 12 episodes in the span of about a week and a half... oh my.
