I don't know what it is about this story but it seems to lack focus and plot structure to me. At first it was pretty easy to follow but now it seems a bit all over the place.
I really liked Nagisas character. He wasn't made to be overly femenine and he wasn't weak or with some major character flaw.
I second that.
This plot is being dragged out so long that I'm starting to dislike the characters. Previously I found some kind of interest in the Lu Xan but now even his motivation seems to be all over the place. I don't particularly blame Jinha or Siwon but both of them have just become so unnecessarily annoying just for the sake of it. I don't know if it's because the plots dragging or because this is supposed to be their core personalities but honestly it's come to the point where it's just boring.
