not the biological father's tho
I mean the Regent Duke Roc thing...that guy
Duke Roc is not the biological father
But the story said it's their child, the red hair man, that Ludwig with her biological mom
Till now it seems so, but lots of spoilers in the comment section suggest otherwise
That duke is not her bio dad. Arellin real father is some kind of immortal, last apostle of the world. He will show up in few chapter before ending
Finally get that stupid biological father's face!!
Anyway love they're bromance (as yaoi fan) that's so hilarious to se them like an old married couple
