I’m Ready for Divorce!

In the original story, the male lead falls in love with the princess of a fallen kingdom on the battlefield and brings her back! Unlike the original, where the ex-wife clings to him and causes trouble after he returns with great achievements, I'm planning to obediently get divorced. I decided to raise the young husband like a youngest brother, send him off to war, make some money in the meantime, and manage the estate well. And I didn’t want to die of an incurable disease like in the original, so I even developed a cure. Now, all that’s left is to get divorced!
