[Buffy ferula gemini]

I’m looking for a story where Buffy was hit with the Ferula Gemini and one half of her is attracted to Xander while the other is not.  I remember most of the beginning at least takes place on the side of a mountain or in the hills.  Xander has quite a bit of the soldier memories still and uses them effectively.   Any help is appreciated, thank you in advance.

[Xander Runs a Security Company]

The one I was looking for, I found soon after.  It was Wild Horses by Jeconais.  I’ll look at your suggestions though.
