Lucius likes Rebecca because of her ambition. I can say for sure that this is a feminist story because when Lucius asked Paul to marry, the first thing that went to Pol's mind was she had to give up her title, lands, and being a knight since she was gonna be the Empress. Before their wedding, she got Rebecca's letter that told her to be more ambitious and not be content and live a happy life, something like that. She went to Lucius again and told him, that she can't be the empress, because she would have to throw away the Winter name. He could take her title, lands, but never her name. She would want to always be a knight with the name Winter since he gave it to her, and that's what makes her the happiest. They separate for a year. Do you know what Lucius did? He changed the laws for Pol and his daughter. Paul becomes an empress consort and knight, doesn't have to change her name. His daughter will be the Empress.
