The eldest princess, Ramona, is clever and kind.
The second princess, Hilda, is brave and beautiful.
The youngest princess, Emma, is a True Princess. She has been taught that one day her prince will come.
Prince Francis could be described as brash.
Iron Henry, the prince's protector, never backs down.
And this all leads to a situation where Prince Francis is desperate to get a kiss to turn back into a prince so he can rescue Iron Henry, while any princess who turns him back into a prince is going to have to marry him. Which is undesirable because Francis may have... tricked her a little to get his kiss.
