I'll get over it by the next chapter, but I fucking hate this one. "The house needs a descendant." "Don't worry, women can have children too." So what ? If that magic didn't exist, if they later decided to adopt, or if Yvonne didn't want to bear children, it would have been justified to force her to marry and sleep with some dude just to fulfill your dumbass noble fantasies ?
Go to hell, asshole dad. You want to spread your family's blood, go spill your own. What kind of family your daughter wants is her choice and her right, not yours to decide, and if you don't agree maybe the world would be better without your name and legacy to stain it.
