I was dumped by the Second Prince, and the King—whose catchphrase is "the incompetent must take responsibility for it"—ended up approving it.

At the graduation party, I was falsely accused by the Second Prince of bullying his true love, and my engagement was broken and I was banished from the country. When I was brought to the royal palace to settle things for the time being, the King then said that while he wouldn't banish me from the country, I was incompetent for not properly handling the baron's daughter who had set a honey trap for the Second Prince, so my engagement would remain broken, and this time I would be demoted to commoner status. "The incompetent must take responsibility for their incompetence" seems to be His Majesty's favorite phrase. But then, who exactly is "incompetent"? ※The protagonist's name has been changed.
