This song is short and sweet, so there isn't much to say about it.
Belle is quiet, polite, strange, and a bookworm. Gaston is loud, arrogant, popular, and a dedicated hunter. Anyone could see they'd make an awful match. Anyone except Gaston.
I think Belle is the only Disney princess to refuse a proposal. Unlike Snow White who falls in love with a guy(he doesn't even have a name!) after singing a duet with him, Belle is practical while still avoiding snobbishness. Even Gaston could sing a duet!
That's why I like Belle so much. She's practical, kind, and bookish.
"Madame Gaston! Can't you just see it! Madame Gaston! His little wife! No sir, not me! I guarantee it! There must be more than this provincial life!"-Belle
