All Comments on 'Another One Bites the Lust'

Liked it... But, I need help! :( I'm looking for a particular story on lit, but I can't seem to find it :( I read it a few years ago, and I really want to read it again (it's like, a zillion chapters long)

It's about a demon that get's summoned by this society to kill this girl because she's doing this uni paper on that society (coz her dad/uncle was killed by them). But said demon watches her through the window dancing to "Obsession" by Animotion, and falls in love or something, and he takes her back to his family's house (i think he's only part demon) to keep her safe... The story goes on, and there's some other bits that involve his brothers and their love lives, and eventually that girl becomes some sort of oracle (i think- unless that's some other story).... I can't remember anything else.

PLEASE HELP ME! I AM EL-DESPARADO!!!! :(
