Queen of Hearts

You're walking through a park when suddenly you fall down a hole. You keep dropping slowly till you land on your feet in some underworld with bizarre creatures living amongst strange and unusual flora. Looking ubove, realizing you can't climb back up, you begin exploring and come across a woman playing Croquet with a white rabbit in a tailored suit. Her tone sounds like she's angry at someone but she's the only person you see to talk to. Can you de-thorn her heart with friendship/relationship?
