Comments of chapter undefined of Protagonist?Antagonist? I Reject Both

Thank you kindly for the chapter 😁

I don't understand one thing isn't it normal for nobility to have multiple partners in the world that Leon stays. Couldn't Sophia's mother just married into Feng family as a concubine if she just wanted to marry into a big family. As a concubine she isn't going to represent the family and can enjoy the riches right.
