I watched 6 episodes of this before giving up on it. The female lead is easy to root for and the usual trajectory of korean romantic dramas means you have every reason to expect her character to triumph by the end of the series. But the male leading character is so objectionable that it becomes ever harder to stick with it. It is also increasingly impossible to believe that she would want to go anywhere near him.
Nevertheless the mismatched couple might have kept me watching.
However, the problems are compounded by virtually every other character offering almost nothing to draw on. Their characters are paper-thin and their behaviours beyond credibility. Korean dramas excel at characters and relationships. It's hard to understand how this one lost the plot so badly.
