i think having a carousel in the video would be cheesy unless its in an artful way...i just hope its an abundance of love stories and how they shape you....a theme vanessa seems to be singing about a lot since h&t.
I agree on the cheese factor. This is how I picture it, hope you can catch my drift, I'm not good at explaining things:
before the music starts the camera is zoomed in a moving carousel so that it looks just like a blur, camera pans out and there is the carousel (still moving). the music starts and it cuts to a couple breaking up. the song than follows either the boy or the girl, (or girl girl, boy boy, whatever) as they go through more relationships and either find each other again, or find true love in someone else. Maybe one of the people is in a park and sees a rabbit briefly, then ends back at the carnival/carousel.
this is just my preliminary idea. I think I'd have to dwell on it a little more to come up with anything else! It's just what I think I would enjoy seeing, not necessarily what I think she would or would not do.
