If humans were truly sorry for enslaving the demon princess, they should offer compensation, either in wealth or political influence, to the demons. But no, the MC, as the human representative, just threatens to annihilate one of the demon empire's countries. Sure, he can do it, but still.
The political discussion in this chapter is totally out of whack. The MC's political skills are honestly just awful.
Also, did that scar face attack another country king? Well, war between demon countries then.
Thank you for the update!
