For Valentine's day; which princess couple is the best symbol of true love and why?

Belle and the Beast because Belle loves Beast not from his outside look. Even her love can turns a horrible beast into a handsome prince.

Tiana and Naveen...They met at their worst and went through some hard times together, yet they fell in Love and stuck it out and decided they would stay with each other no matter what....They were not with each other cause they NEEDED to be but because they WANTED to be and they fell in Love with each others personalities and inner selves. Also they were willing to sacrifice their past lives and families and everything they had to be with each other, even though that meant living as frogs in a swamp for the rest of their existence... So I believe that Tiana and Naveens relationship truly shows the meaning of True Love! (even though Naveen is not my favorite Prince and I want to kick him)

Eugene and Rapunzel Fitzherbert
This couple is the best symbol of true love because first at all it was not love at first sight. She was afraid of him. He sees Rapunzel as pretty, but he only wants to leave with his satchel. They were united for that alliance in Rapunzel going to see the lanterns and he having back his satchel. In their journey, they starting to become allies. Later, they understand themselves like friends. Now, both of them, realizes how important are each other. Rapunzel see a nice man that have feelings, who is afraid to talk about his past because he didn't have the best childhood. She fell in love with this nice guy Eugene, and not the selfish Flynn Rider that she was scared. Eugene (Flynn Rider if you still prefer this name)sees Rapunzel, besides been beautiful, as a honest, nice girl who only wants to make her dreams can true whatever she had to do. He sees her as strong lady. Now Eugene wants to make her birthday as the "BEST DAY EVER", and he was succesful. He only cares for her. Rapunzel enjoy her birthday, but now she feels that it was better with Eugene at her side.When Eugene saw the Stabbington Bothers, he cares that they don't want to hurt Rapunzel only because of him.She was really in love that when the Stabbington Brothers show that Eugene "leave" her, she was heartbroken with this. She even cares about him when she asked what happen to Eugene to Mother Gothel. When Eugene wake up, his first thought was Rapunzel, worry that the brothers maybe kidnapped her. When he discovers that the Stabbington Brothers were in jailed and found that all this was made for Mother Gothel, he tries to escape to save her. When he arrives to the tower, and found that she was tied,Mother Gothel stab him. Even that he was hurt, he tries to move to do something for her. Rapunzel been see that Eugene could die, she offers her freedom for his life, even that she knows that maybe she would not see him again. All matters is that he is alive. Eugene knowing that she will not break her promise, and that she would not be free until the hair that united Rapunzel and Mother Gothel, he decides to cut it. he knows that he will die. If she is free and better, he would die for her. At the end, they are together. He risk his freedom to take her to her parents (The good thing is that he was pardoned, and he was not arrested)Risking life and freedom, it really show true love. Not everyone will give that for someone else. This show that Eugene and Rapunzel are really in love, and the love will continue.
