One thing in deplore with manhwa like this are that the siblings of the MC rarely get their own loves and family... Apparently he isn't even the heir of his house despite being the older one... Is it so hard to give siblings SO?
One time I read here that Karl Aslan is the Executive head of the Aslan family and Beaty is the Nominal head along with being Empress. In short, Karl actually manages the dukedom since he himself said that he is busy receiving heir training from the Father, to carry the workload of a Duke.
