The story's timeline is set in the medieval era, or closer. What's not considered acceptable today was completely normal for those back in the day. It's completely understandable to not accept the ship as a person of today but we can't apply the same social and cultural standards we have in the contemporary period, to eras such as this. Otherwise, it wouldn't be realistic at all (Which I assume what the author is going for lol)

I completely disagree with the ship of the mom and the blond.
The blond and Anna are cousins! Doesnt matter if the mom and franz are NOT related, by family relation, thats still weird.
If Carla was married with Anna's dad, Franz would be her nephew. Morally, its wrong.
The problem here is that her daughter is RELATED to Franz. If they werent related, no issue.
The age gap is not the problem, its the family relation!
