You think changing stigma that rooted since the country founded is as easy as flipping the back of your hand? That will take at least two generations of the rulers!
His omega son doesn't have the time for that. So marrying him to a country known to cherish omega will be a smart move. His son will have more opportunity than if he stay in his homeland. Besides, where do the king has any spare time when the country has problems that lead to now critical condition.
The king certainly isn't the best father, but surely he did what a father will do.
You are missing my point. He had the capability to care for his son as royalty and at least teach his other son basic decency. This “coming back to the homeland” arc is a means for the author to prolong the story and provide closure for the protagonist’s earlier mistreatment by his family.
Frankly, I believe it was done poorly and just excuses the king’s actions.
In my PERSONAL opinion, I don’t find their actions realistic and I would definitely not forgive my father for marrying me off to a stranger (they still exchanged goods- riches for a bride ).
For me, this argument has reached its end. You do not seem to comprehend what I am saying and that is simply it. The literacy skill comment was childish at best, considering your arguments. Have a good one and goodbye

He loves him and wanted to protect him but still sold him to another country and only shows up now. Make it make sense
