I have not enjoyed a Korean drama this much since City Hunter. I will start off with the OST. I rarely pay attention to the OST because they dont seem to catch my attention ;). This time though I realy felt like listening it over and over. The acting was realy great (imo). From the lead actors to the supporting ones all played their role pretty well so it was a joy to watch. And the story. Nice twist and turns, some unexpected things. Aaaaaaahh the joy not being able predict everything is great! I realy recommend watching this one.
