I enjoyed this a lot. The way you switch between Clint’s and Nat’s perspective is great and works very well for this story.

Do you have an idea as to how you want to end this? Personally I would probably write one more paragraph where they make up in a way that’s … well, I don’t really know how to phrase this. My head!cannon is that they won’t talk it through, because that would mean that they would have to admit their feelings for each other. So there might be a small gesture of apology and then Nat will simply forgive Clint, because he’s Clint and they will simply be professional about it. This could then lead to a second chapter/follow-up story where they have another big fight because he’s overprotective/she has endangered herself in the field (again) which ends with them finally talking about the issue at hand (aka. their feelings for each other). But then that’s me in need of drama with a happy ending. ;)
