Such a disappointment! A super interesting premise that goes down the wrong road with poorly defined characters, cartoonish & unnecessary chase scenes & violence. Of course, in similar fashion to other shows (like Vagabond), characters can be stabbed, in car accidents and beaten to a pulp, but everyone instantly recovers. And at times characters can easily stay off the grid, that is unless someone (or the writer) needs to find them ASAP.
What saves this is the great performances of the two leads. Yu Na and Yoon Kye-sang.
Glad this was only 12 episodes and virtually all are 60 minutes. With so many great stories/compelling Korean drama's, check out the far more entertaining Reborn Rich or Start-Up for light weight, but wonderful shows.
