I think having a flippant princess who's constantly flip flopping between her gang of "true loves" would be really funny. I think it'd actually be way better if she legit thinks she's in love every single time, without a trace of self awareness, though the other party members themselves wouldn't take it as seriously. In her mind she's going through a harrowing quest of conflicted romance, being torn between her various "true loves", while to everyone else she's basically the party bicycle being passed around, of course they all humor her and play into it, because she is a princess after all, so why not spoil her a little?
