I mean, herp derp here. He was willing to die just so she could be free!! Mulan/Shang as well, but I hate the sequels, so whatever happens in them does not count in my eyes.

Rapunzel was going to give up her freedom so he could live and Flynn gave up his life (although he revived) so she wouldn't have to be Gothel's prisoner.

I don't have to restate the obvious for Eugene/Rapunzel. Mulan and Shang def proved their love for each other in Mulan 2, but it doesn't count b/c it's a sequel..

Really, the answer is obvious, especially since Shang and Mulan's relationship doesn't even start until the very end of the movie (so no opportunity to prove anything for each other), and the focus of the movie Aladdin is not really the relationship betwenn Aladdin and Jasmine, it's the friendship between Aladdin and the Genie.

I mean Flynn sacrificed his own life to free Rapunzel from Mother Gothel's hands, for a thief like him that was one brave and selfless decision. And Rapunzel who has been trapped in her tower for 18 years she sacrificed her own freedom to save the one she loves. What they did was that bravest thing i have ever seen in my whole life, it's a bit too much to you but to me it is.
