I have been looking all over for it! :( I remember the girl was with the werewolf at his house they had a fight in his office and she runs away out the window from her room at night. I think she goes to school the next day and vampires show up and I think they end up kidnapping her. The vampires eyes were all illusions, like a starry night or sunny day and stuff like that to help them attract people, and then in one scene she's dancing with one of the vampires and they both sing to this song that I can't think of at the moment :( she ends up back with the werewolf near the end, I think they meet at a graveyard (?) and they do sort of an exchange where he gets her back.
