I don't want the king with the red head snake either but I want them to come together to have their son. How is it gonna work?
They can marry, have a son, then divorce. Or maybe let the snake head will die instead of father??
orrrr the villain can be born with the MC since he is a copy of his father looks and not his mother looks.
I my opinion, whenever they show the son, it's never with much detail or personality. So I don't think he will necessarily be born, though I would be intrigued if he was.
