@Shruti Because normally, they either all have as g** role in the story. For example, a queen/king/emperor/ or an empress will always have a ridiculous amount of money. For they are high nobles, the highest of all and people may respect them or dislike them, but they may only show hue much they hate the higher ups in silence. In this situation, she is the daughter of the Duke. The Duke is a very high, strong, and an important role aswell. In that case, it makes sense that she'd be bawling with money everyday
