Daisy, the Pampered Young Lady's Decision and Happiness

Born into a moderately noble family and raised appropriately, Baron's daughter Daisy spends her days as one of the young ladies surrounding the aristocracy. While doing so, she hears various rumors. After a certain count's broken engagement, news of another country on the brink of ruin, and one day she hears rumors of a marquis on the frontier suffering from illness. He is said to be a savage man who thinks only of war, and even his beauty—the only thing he was praised for—has been lost to illness. Everyone around Daisy opposes an engagement with such a man, but her older sister, a former member of Daisy's circle whom she admires, tells her that if an engagement proposal with him comes, she should accept it. Confused, Daisy receives a proposal for engagement with the frontier marquis. Should she wait for modest happiness as one of the young ladies in the circle, or should she marry the frontier marquis and believe in extraordinary happiness? What ending awaits Daisy beyond her decision?
