This is just my opinion.

I think the storyline and main characters build are very poor. I’m so disappointed. I dislike everything the mains characters do and the decisions they make to keep the storyline going seems so stupid i cant stand it. I feel bad for taking my anger out on the casts when I know its just an acting. I also think that the male lead need to take care of lotta stuff while the female lead have a very little purpose on this drama. However I keep on watching because I want to watch Lee Dong Wook and Kim Bum. I like the supporting cast backstory and characters build much better. They outshined the two main cast as they are more interesting. As for the ending, I’m utterly dissatisfied.
