Thank you for picking this up. Everytime I read this, I wonder which person will be the first person to learn about Vio's circumstances. As it stands, both Vio's maid and Yulian are already aware of it, and I suspect the series will end shortly after the prince is made aware of the situation, so most likely, the younger sister will learn of it first. If this happens, as she is shown to be not the brightest when it comes to high society, she will do something seemingly dumb to protest the recently perceived injustice, such as asking her father why. However, this will somehow impede Vio more than anyone else, so I do look forward to the rest of the series.
