Spike lives with Buffy and Dawn and Riley shows up at buffy's work a bookstore I think.

I'm looking for a fic that spike is living with Buffy and Dawn and and Buffy is working at a bookstore I think. Then Riley shows up and Buffy calls some to let him know so then we see him chain smoking and pacing the living room while dawn follows behind him. I think at the end we see dawn and Giles dancing at Xander and Anya's wedding looking like a couple.

Footprints in the snow by dauntless grace has buffy working in a bookstore and living in an apartment with Dawne after her mother dies
