Bucky has never seen you mad before. Not when you two were just friends and avengers together, not when you were fighting once you started dating, he just never saw you get angry. Frustrated, yes, maybe a little pissed, but given everything you went through you’re ridiculously emotionally intelligent and good at self regulation, you’ve been dating over a year now and Bucky is genuinely starting to think anger just isn’t an emotion you feel. However, when he throws himself in front of a bullet that would’ve struck you clean through the heart (but only nicked his shoulder) it’s like you’re actually vibrating, you’re on the ride back and the tension in the quinjet is palpable as you pilot it, not able to even look at him. The rest of the avengers are either nonplust or pretend they are.
