I read this Gossip Girl fanfic once with Chuck/Blair (Chair

) where it's been like years since they've seen each other, she's involved with someone else, and it seemed like they both moved on from what they had, but the feelings and attraction return (slowly) and it's complicated. They resist it initially I think, they've both changed afterall, but in the end he totally fights for her.. It was a bloody hot read..
I'd love some Spuffy fics like that. Where Buffy is involved with someone else and by chance Spike pops back into her life and it's a complicated, angsty hot mess.
