Wait, how is Geraldine a relative on the mother's side if he has the last name Floyen?

Thats true but its more common in the olden times bcs class distinction and preservation of one’s noble name was really emphasized. So if the family name was prestigious enough for the empire and over the paternal family, it’s very possible. Or if the man is a commoner getting married into a highly esteemed family.
Bro I love the comedic effects in this manhwa
