The comic says that mixed blooded ppl like him are like mules, cant have babies. (Or cant have babies if its not from that blood)
But thats funny bc on other places it says that all ppl have mixed blood in some ratio. And how did they came to be if not mixing mixed blood even further ╮( ̄~ ̄)╭
Well nvm that. Lets just accept that.
So the other thing that they state is that only the princess has pure blood amongst all the ladies, therefore she is the only one not being able to have a baby with a mixed blood person.
(This is also funny bc the royal family doesn't marry between themselves either. It gets mixed with other noble families' bloodlines → so it has gotten mixed with mixed blood too. :$ I guess we should just not think about the logic ^^)
Hope yall could follow my long-ass reasoning. XD

Like actually is he infertile I do T why he can't have a baby smthn yada yada
