It's a story where Tony can see the red string of Fate, around the pinkie fingers of everyone. He spends his entire life thinking he'll never have anyone because his kind of just trails off and never meets anyone, and he tries things with Pepper until he sees her thread going off towards, I think it was Happy. And there's a side pairing of Clint/Coulson (where in, Tony notices that Clint's thread is still there/red/pointing at Coulson even though Coulson is supposed to be dead). His - obviously - points at Steve but he kind of ignores it. This is where my memory gets fuzzy.
I remember vaguely, Steve chilling out in the lab with Tony and Tony finding his sketch pad and seeing a picture of him looking down at his hand and there being a red string looped around his pinkie finger and he's like ... until Steve tells him that Bruce told him about the legend.
All that, I remember. The title, nothing.
And all google can tell me is that it's apparently a popular media thing for Avengers fic and not one that's been written.
