I'd rather continue the story without spoilers and see where it ends but I don't see any way of Lucius and Paulina ending up together, and even if they did it wouldn't be in a good way due to the society they live in. It would be nice if she could marry a man who accepted her as she was without having to ask of a sudden become a feminine maiden, but due to her circumstances she decided to not get married and have children, going against the status quo. I like how realistic this manhwa is in its portrayal of a patriarchal society and the rigid rules of nobility. I wouldn't want her y to end up study the emperor anyways. His responsibilities would always get in the way
