In classic fairy tales, it wasn't uncommon for the main character to end up in an incredibly unhappy situation only for a Prince Charming type to swoop in and suddenly solve all of her problems.
More modern twists on this trope don't always make this person a prince (the world is kind of running out of those), and some will depict this relationship as a little more complicated than simply "happily ever after" but the fantasy still exists.
And although there's nothing necessarily romantic about what one Australian millionaire is offering, those who feel like Cinderella right now might be tempted to see him in a similar light.
