Story

Ah, the headstrong Charlotte Augusta? She really doesn’t seem like an Augusta at all. There’s a reason she still has no suitors even after three seasons in society. Charlotte Augusta, the third of the five sisters from the renowned Augusta family in British high society. Charlotte, who was treated like a black sheep among her beautiful sisters, causes a major scandal at a ball she attended—as usual—in search of a husband. And there, she meets a handsome man with a refined charm.
