Cloud Nine, if you read the rules on our main site you'd see that here on The Spuffy Realm we consider a fic 'Spuffy' when it's a story revolving around Spike and Buffy. In no way shape or form does that mean Spike and Buffy have to be in or end up in a romance. In fact they can absolutely hate each other, so long as they are the central characters and the story revolves around them.
I'm sure there are Spuffy sites that are all about the fluff and love, and you will find that probably 95% of the stories here fit that criteria, but it's not a requirement here. Spike could kill Buffy, drain her dry, and then dance in her blood, if he likes. Spuffy can be enemies, some of the best Spuffy moments on the show came during times when they loathed each other.
Now, please let's focus back on the original poster's query, thanks.
