Gotta say the the enemy king is pretty freaking stupid. Whole reason he invades the country is to make the princess his wife? Never heard of diplomacy? Political marriage? Because her father literally didn't give a shit who she married as long as they weren't hostile and proved themselves to him. Instead it "Give yourself to me or I'll kill everyone close to you" *rapes her* "Are you going to keep your word" "Oh lol nope everyone and everything you've ever known or cared about is either dead, on fire, or both. BTW you better be my loving wife now and I'm looking forward to a happy life together"
