His Majesty: "It is you, after all."
Reader Translation: "Whatever you do or how dummy clumsy or clueless you are, it's okay, I won't acknowledge your mistakes & there won't be any punishment because you are my chosen, only waifu. Therefore it's all just a misunderstanding & I'm backing you up as the Demon King, & nobody will dare to oppose my absolute decree (about my waifu and her cute mishaps)."
& the girls keep saying she's of low status even though her hair & eyes clearly showed that she's pureblood & her scores keep topping all of theirs. Jealousy is blind, huh.
Btw, none of the people in the castle surrounding the king trustworthy. The guards didn't even know their own king. Is he a hikikomori (LOL)?
