Why must her sister get with the prince for her to become a nun? I've forgotten. If they need powerful connections, there should be other high-ranking nobles anyway? No need to panic. Improvise, adapt, overcome! Is she super inflexible or what.

It’s because she needed her father’s approval in order to become a nun, and the jackass won’t give his approval because it would tarnish their reputation. The only way possible for her to become a nun without drawing too much attention to herself is if her sister marry the prince. With the sister marrying the prince, all the father’s attention would be on them and therefore he would not care about what Vio is up to... or something like that.
Who's the mother of her little sister? They look so alike but not like the father at all. I assume they have different mothers but they look so alike.
To my understanding, Rubiel is the child of the main wife. But it think the main wife's dead and Rubiel has a stepmother because she mentioned that her dad's wife doesn't like her
