I feel like marie likes the prince, after all no matter how good your eyesight is, being able to find them in a sea of people only happens when you've memorized their figure from head to toe, meaning you look at them a lot or u observe them a lot

You mean Mio. Marie doesn't even know the Prince or how he looks.
Anyway, I don't agree that she likes him. She seem disgusted just mentioning his name.
