Brooooooo. You are the fuckin' HERO. So you got an arranged marriage, no big deal. You get heroically married and kiss the princess, heroically. And then live happily ever after. That's the hero grindset.
You didn't have a "fake" wedding. You had a heroic real wedding! The kind that becomes a fairytale to your descendants! The kind that gets you and her a statue to remember the peace you maintained and granted to the land.
So fuck what the king said. Go bang your big titty trophy wife, stay on that sigma hero grindset and slamjam all over that stupid book.
