I was transmigrated into the handsome and powerful Grand Duke of the North in a romance fantasy novel. I thought my happy second life was beginning, but the finances are in the red every month and there's no time to rest because of monsters. For my peaceful retirement and early resignation, I must turn this damn territory into a profitable one. "Your Highness! We've seized all the assets of the embezzling nobles!" The story of the Northern Grand Duke who works the genius finance minister princess and the battle-loving Northern territory residents to develop his domain. The cover is fan art that Albap-nim has permitted us to use.
