Bucky Barnes / Clint Barton
Bucky was pleasantly surprised that he and Clint had just been so effortlessly happy together. They both had their fair share of issues but they didn't affect the relationship they had. If anything it just made them stronger together. If they did (eventually) get into a fight Bucky had every confidence that they'd be making up for it pretty fast and continuing on with their blissful married life soon after.
"As a matter of fact, it did involve tearing your clothes off. Only. you can't rip mine because this is the best shirt." The flirting; god, the flirting. It was so much fun and everything he said to Clint just rolled right off his tongue; he didn't even have to think. It was so good to be able to tap into that flirty side of himself that had for so long lay dormant to the point Bucky didn't think it existed anymore. "And I can guarantee a shower's gonna be required after."
