Well. From the first time I've heard this song in the movie enchanted, it really made my heart melt. I guess this song just expresses a feeling of so much love, but it's forbidden. Just like the situation of robert and giselle. Robert got nancy and giselle have the prince. Though they have thier own "partners", still they feel something for each other. When they danced at the ball. This song was really telling their story.
