Need to know

No, he just doesn't know how to talk

Why did he call her a “useless thing” and leave then? Is that ever addressed between them?

Also, is he a good father to his sons? She said he doesn’t love his kids, only his wife

It's explained more in later chapters
I'm not sure. There hasnt been much focus between him and his sons, there might be a chapter that focuses on that but not yet

Can you spoil me how they explained the „useless thing”? And the „he doesn’t love his kids”? I kinda rather know that stuff before I commit to a story

useless as in she cant learn the sword technique of the family since she's a female, and shes gonna die early. it is mentioned that the next day after giving birth to isabelle he apologized to the empress profusely for hurting her feelings. i think he didn't want to get too attached because she will die at 21. he is really bad at feelings though. the empress has to peel them out lol. biaton his aide made him feel really bad about what he said, saying that she remembers everything she has seen and heard since she was born and telling him that just because she can't learn the sword technique doesn't make her useless and he was awful for saying that. he makes it up to her by spending time with her, especially making time on her birthdays and wishes he can make her have more time than she has left. also getting her a magic teacher. they don't raise all the kids with a lot of love though from what i can tell. they all get raised in a separate palace once they turn like 5 or something i think. we've only met like one of her older brothers that she lives with because the others are out doing stuff. he really only pays his attention to isabelle thay we've seen.

What chapter does aid confront him? Also, it’s still a pretty bad reason, but I guess forgivable if written well

idk like 5 or 6 maybe? its very early on.

Thanks!
