The daughter who was married off to the fearsome duke as a substitute for her sister-in-law is far too manly.

In the wealthy Kingdom of Andalde, there exists a man feared as the "Viper." He had been lending money at low interest rates to various nobles, but the Marquis of Faldis family had fallen into financial difficulty due to business failure. The Viper Duke presented the Marquis with a condition in exchange. "If you give me your daughter as a wife, I will forgive your debt." However, the Marquis, who doted on his daughter, attempted to substitute a commoner named Ricarda in place of his own daughter... but this Ricarda was far too handsome. ※Thank you for 1st place in the overall rankings for 16 consecutive days as of August 15, 2024.
