It is a matter of differing perspectives.

Being born into a ducal house comes with many troublesome matters. This time, it's a marriage. Along with pressure from the royal family, they told me to take in a good-for-nothing. Well, I managed to extract reasonable conditions and obtained something decent, but in the end it became a hopeless piece of defective goods. Finding this truly unacceptable, I petitioned to cancel the engagement, and His Majesty said this to me: "That is a difference in perspective." I see. A difference in perspective. What fine words those are. Opinions differ on various matters, and perspectives vary from person to person. I received approval that the royal family's thinking and my ducal house's thinking are different. So yes, this is... "A difference in perspective, Your Majesty."
