Not enough "duo" action when taking into consideration the 32 episodes runtime. I don't feel the drama managed to accomplish anything with its story. The entire drama was structured around the duo but we barely got a few "duo" moments. Their paths don't intertwine as often as you might think. On the other hand, I found the romance quite problematic. It overshadowed big parts of the story and ruined some plots more often than not. Love interests and romance rivalry were two poor elements the drama tried desperately and continuously to shove in our faces. Of course, the ending was terrible as expected.
