@SpaceFootballKing The numbered rank system seems to be a court rank system. While it's somehow tied to the peerage titles, it's also related to the folks' position in relation to the royal court and government. So, one could be a baron and rule an island but have little to nothing to do with the court. Or one could be a baron, I assume, without having large land possessions, but have a position in the royal court (like a minister) and a high rank.
@Ekfreet It would be weird if Livia and Angie weren't being prepared to both marry Leon, seeing how they get along so well. Some of their scenes could be from a yuri manga. I can judge it as nothing but those two actually gladly sharing Leon if needed. I usually dislike harem, but I wouldn't mind those both marrying Leon. One of the biggest reasons why I dislike harem, after all, is because I don't see it working, unless it's the kind of harem that existed in RL in Middle East and elsewhere, with the women being little more than prisoners. However, Angie and Livia like each other very much and both love Leon, so I could see it working, especially since Livia is timid and selfless, whereas Angie's experience with the prince would have brought her feet harsly down on the ground. In contrast, Marie's reverse harem looks like bullshit. There's no way those five spoiled guys should like to share one girl with each other, plus with the bloody slave to boot.
