Okay, from the raws that I've seen I don't see why this would be called Stockholm syndrome. The prince isn't abusing her, he isn't threatening her or even harming her in any way. All he's doing is catering her every time she tries to run away. In fact he looks likes he's having fun. If I were to guess how this story went, the prince actually fell in love with her in her tomboyish state, but when she came to the castle the people training her to be princess tried to suppress her "wildness". The probably started to wonder if she loved him, and he wanted to make her jealous, only it back fired, so no he's meeting her head on. I think he actually likes her "wildness" and is finding more interesting than her "perfect princess" act. Of course the FL doesn't see this and is trying to be free because she doesn't know how the prince really feels. But so far I don't see anything to with Stockholm syndrome. As for the girl the princess brought to the ball, she has more boobs than brains and seems more pissed about taking the FL's place than happy about it. This is just how I see it.
