Forever and a Day by Lilachigh
New Year's Eve in London. Buffy has arrived in England needing to rest and find some purpose to her life. A meeting in a dark street changes her world for ever.Part 3 of the Long Distance verse is about New Year's Resolutions (kinda) but it is where Fred is nosing at their emails rather than them being in it as such (all short and smutty fics).
