There Are Strangers I Have Yet to Become (слэш)

"Two days," Steve repeats. His words are slow and almost gentle, and there's a small smile starting to form on his face again. "I'm asking you to let me stay here for two days."
Bucky frowns.
"What? Why?" Bucky asks. "What the hell is that gonna do?"
"Remind you what it's like not to be alone," Steve says. His smile looks sad when adds, "because it's been a long time since you weren't."
"That's not gonna change anything," Bucky says, swallowing hard. Steve's words bounce around in his brain. It feels like they're hitting up against spots he hasn't uncovered yet.
"Then you've got nothing to lose," Steve says, raising an eyebrow. "Right?"
(Or: Steve finds Bucky in Bucharest before the events of Captain America: Civil War. They work a few things out.)
