Where do you think that payment is coming from?

"I found true love! I'm breaking off the engagement!" the Crown Prince announces loudly. But the dress and jewels he gave to this supposed true love were all purchased with our family's money!? The moment Celestia, the daughter of the Duke's family who supports half the nation's finances, decides to abandon him, the loans granted to the royal family are immediately switched to full repayment. "Love cannot save a nation. What can save it is――responsibility and practical competence." A refreshing reversal story of a Duke's daughter who supports her country with the power of money!
