There is indeed a Cinderella here, but... What if her situation is not because of her stepmother or her two sisters? What if the person who was with her at the beginning was the predecessor of the Frog Prince? What if the magical fairy was transformed from the happy Snow White? What if you meet the prince from the story of the Mermaid Princess? ... How will the story end?
Maybe what made Cinderella become a princess was not the fairy, the glass slipper, or even the prince, but her heart that wanted to become a princess.
