They would get along very well. They're both mature, romantic and try to do the right thing. They're both quiet and not adventurous so they wouldn't have many disagreements on what to do for fun or anything. They would find each other's hope inspiring, and relate to how crushed they both felt when Cinderella's dress was ripped and she couldn't go to the ball, and when Aurora found out she was a princess and any plans she had for her future were gone.
I think they'd be best friends. they have a lot in common.
