This is precisely why I love Kristoff, and just Frozen in general. Disney’s poking fun at their older classic princess films, and at the same time changing the “rules” to a better and more contemporary mind-set.
But um let’s just be reminded though that Belle lived with the Beast for several months. And she didn’t marry him at the end of the movie.
Yo in Tangled’s closing monologue it explains that Rapunzel and Eugene had a relationship for awhile before they got married
Anita probably isn’t a good example either
It took three movies for Jasmine and Aladdin to get married.
