This fic goes canon divergent for everything following Mary acting as a client in His Last Vow. Sherlock misses John. John misses Sherlock. Victor Trevor, Sherlock's oldest friend (and a super nice guy in this version) and participant in the 'great sexual experiment of '98' shows up to cuddle the hell out of a touch-starved Sherlock, get him talking, and get those two idiots back together. He'll work on Mary later. One fucked-up couple at a time is all he can handle.

Three weeks after their wedding, they give Sherlock a ring.
