Buffy travels back in time for Spike

I have used the search function here and at Elysian Fields and am coming up empty. Maybe because I have been out of reading in the fandom for awhile, lol.
The fic I am looking for is post Chosen (might be post NFA - can't remember) and Buffy, having realized her feelings for Spike, travels back in time to Season 6 landing in the alley during Dead Things. I honestly can't remember much more than that. I am guessing, since I rarely read any other rating, that it is rated NC-17 and I know that it is a Spuffy ending. Thanks in advance.

It could be Beggars Would Ride by ems4179 - https://www.fanfiction.net/s/7032105/1/Beggars-would-ride

The part where she goes back to Dead Things is Chapter 13. I haven't finished it, so I'm not sure if it's a Spuffy ending or not.

Nope, that is not it. I have never read that one.
The fic I am thinking of is specifically related to Buffy going back in time for a second chance with Spike. It is also, like I said, more than likely a NC-17 rating which means it will more than likely not be found on fanfiction.net.
Thanks for trying though.

I don't know why really but this one come to me after reading your post...
Shades of Heaven by hollydb
A vampire given a new life, a Slayer given a second chance, and the passionate fury in which they come together.

That is a good fic but not it either. Shades Of Heaven takes place in early season 4 - Both a post Chosen Buffy and a resurrected and freshly corporeal Spike are both transported back to season 4 into the episode The Harsh Light of Day by Anya and a Hysl'ik gem.

The fic I am looking for, Buffy is the only one to travel back in time and she travels back to season 6 landing in the alley during Dead Things.

The Wisdom of Years by Arina Summer has Buffy sent back to Older and Far Away from post NFA, (starting off with a big confrontation with Angel about his past year at W&H then whistler comes and gives Buffy the choice). So not Dead Things but one of the first things she notices are Spike's injuries from her beating so it could be that you are thinking of that one as this is commented upon basically as she arrives. But it definitely didn't return to that actual alley scene so if you are 100% on that, then this isn't it!!. Unfortunately it is no longer available online and it is a dne.
