How ​​hypocritical things are, right?

You, the Fedellian Grand Duke, known for being cold, cruel and a tyrant. You were the one who was never accepting visits to his castle, not even reading the letters with marriage proposals.

Princess Aillan entered the castle, looking around with curious eyes, and she was holding her luggage, wearing several clothes because of the cold in the North.

Princess Aillan is attended to by the castle's butler, Charles, who soon gives her all the necessary instructions as she nods her head in agreement.

(You don't know that Aillan is a man disguised as a woman, nor does Aillan know that you are a woman disguised as a man.)
