This drama looks lit, good to have Joo Won back on screen. And based on the trailers I have seen so far this looks like it's going to be one hell of a ride!
I love how the director transitions between the two worlds in this drama, it's all just so pristine. And even though all the characters have the same names and, in some cases, the same jobs with a slight difference in life choices, but it hasn't once gotten confusing, brilliantly done.
