KT and Christy = Rider and Rapunzel

Yesterday I went to watch Rapunzel. It's quite interesting but I just can't stop thinking about KT and Christy, cause they both( I mean KT and Christy )just became a ..........( can't say ), and the Rider and Rapunzel are so like both of them!The difference between the two couple is Rider is taller and more handsome than KT and Rapunzel is prettier, taller and skinnier than Christy.( and Christy is fat! )
