Um, the heck are Luna doing?
Well, it would make sense if she really doesn't have any power to fight back (real physical/magical power; not political power of course, she does it in the first place), but not trying anything to escape, like running or maybe jumping out of window or at least yelling help, is basically giving up herself. Furthermore, she tried to commit suicide which is a dump act for me, there is a chance for her to escape the situation. But yea, I know, getting raped is a really bad thing and can affect your mentality (it can last forever too), but huh... I don't know why but I think dying will be the end of everything she has. The bullies win, no one has the evidence of the bullying, her parents will be sad, and maybe, just maybe, the kingdom stability can be shaken (well, since she is a marquis' daughter, there's a little chance her death will be causing another problem).
