i think this song is about foreseeing the end of a relationship. But she doesn't want it to end, or him either, so she has break-up sex with him "the last day of magic" to spark the relationship back up again. but she can't find his passion there, his love for her is now non-existent "where are you?", and she longs for the love he used to feel for her. but right now she's just having sex with him, and she feels all of this going through her head.
