Both Giselle and Rapunzel are just out into the big world, and both Robert and Flynn are worldly-wise men. Giselle and Rapunzel are at first innocent, but then become smarter. And they have adventures with their lovers.

He's grumpy like Robert, and she's light hearted, although not so much as Giselle.

^ That's a good call. Hell, their ballroom dance is almost like Beast and Belle's, from what I heard.

I say Mulan and Shang, in terms of Robert being more savvy, and Giselle being more energetic. Although Mulan's a bit more grounded than Giselle.

It started out with the boy not liking the girl. Then they became friends. Then they fell in love! <3
