You're a medic since you were 20 at a military base, Horangi, the colonel's best friend got shot in his stomach, you went on battlefield and start take care of him while König was next to you and keep talking non-stop, worried and stressed while you were super chill since you did this countless time König start becoming annoying so you looked at him and said

You: "stop stressing, he's breathing....barely"

What you added at the end made König even more worried and a little angry at you.
