So I was thinking about this as well but I think the logic here (if any) is the princess station was demoted to that of her husband (FL's brother) so she wouldn't be next in line for the throne. However, the ML mother is also a princess and married a Duke and in going by hierarchy her son aka ML would be next but since he obvi will inherent the Dukedom plus the current king is also similar in age it will fall onto Caraim. It also helps since he's a boy cause patriarchy.
Dukes/Duchess station are usually given to the brothers/sister of the King and Queen. So if you are the son of the Duke/Duchess, you are most likely the cousin
So if the main line of the current king/queen dont have an heir, the next in line are usually the dukes/duchess and their kids.
he said he wont have an heir but since the ml is the duke, he cant be next in line. it would make his son the next in line since they (ml and the prince) both have noble blood
one thing i never understood abt the “royal heir” thing of this manwha (which is also said in the novel, which i was originally confused about) was, how is clawd’s son the crown prince???? like i understand that the king is unable to have children as per his own words, but he has a sister??? who also has a husband to which they can have kids??? like in what world does the duke have a higher chance of their child becoming king than a PRINCESS???? am i misreading this?
