I think this song is about a girl and her dream boy, and the things he'd say to her. She's trapped and wants to break free, "having no regrets is all that she really wants," but her parents are controlling and wont let her. This dream boy is so full of fun, which she loves because she wants to break out and get crazy, so crazy that insane things happen. But when such things happen, she'd be scared it might ruin the relationship, so her perfect guy would be telling her that it wouldn't change anything between them. In conclusion, its a beautiful song about the voice of the fantasy, the perfect guy in the mind of a girl who is constantly held back and controlled by her parents.
