I started this drama because the storyline seemed interesting, but as it turns out, a promising story can be made into a boring drama if you put enough effort into it. I've watched a couple other long(28-30 episode) dramas before without much trouble, but this one was more a test of patience. The plot crawled along at snail's pace, with situations, cliched as they were, happening over and over again; even the characters seemed to be bored of repeating themselves. I couldn't sustain beyond halfway. It didn't seem to be worth the effort beyond that.
