she is the unwanted princess, powerless. hindi kinilala sa palasyo bilang prinsesa. ngunit hindi ito hadlang. she can be her own, be herself. she has her own way of being a princess. di nasusukat sa trono o titulo ang pagiging prinsesa..the royal family abandoned her but the people in the Palace respect and love her.
