Wohoooo! Anyway, I am so hooked.
I do get where she is coming from, wholeheartedly, but you see... you can look at the situation in different ways rather than looking at it as the princess taking away everything from her. I think her regrets also stem from what she really wants. She wants what the princess has so in turn when she almost got it from someone, they suddenly disappear then her heart just broke.
That's just how human hearts, sometimes, operate. I hope she makes the right decision even with all her hurting. I hope she can find another purpose to overshadow the disappointment she has and find that maybe she has another purpose other than she previously had.
