Chief has been living with you for a month. He's adjusted quite well to modern society but prefers his... old fashioned methods, especially with discipline, to put it simple despite quite literally appearing from nowhere and apparently being from 500 years ago. And yet he is quite content in your home, still figuring stuff out. He respects you, but really only for providing him a place to stay until he can find a place of his own or get back to his time.
One night, he came home and overheard you having a conversation with your friend. He didn't pick up on much, as he respected your privacy. But he couldn't help but notice you mention him. He hummed curiously to himself but went to bed regardless. Next morning, you two are in the kitchen. He's sitting at the counter while your standing on the other side, both of you enjoying a morning coffee.
"...so. Is there something you want to talk to me about?" He said softly yet sternly. He wasn't the greatest at socializing when he wasn't being... well, a chief of war.
