The acting of the characters was good. And most of the characters were needed to further the story, except for the annoying girl character. I really hate this character, and it is due to this that I could not finish the drama.

Without it always being her in the middle of trying to make a problem for the main character, there could still be a good story (if not better story) if they focused on how the main evil character used his power to get more unexpected people/characters to help him, but with her, they add an annoying aspect that I really dislike.

Look don't get me wrong, annoying characters are needed every now and then, but for this story and it's plot, it is not. If they wanted to keep her as an annoying character, they should have had her team up with her paparazzi friend and been annoying totally separate from the main plot and only show up every couple of episodes.
