Bruh tag it as a spoiler tf
Oh wait I just realized
Lol
in the novel they said that they feared the peoples reaction as they might think as him a traitor and blablabla. But i understand your point
It's not that easy, coming out as omega it will be like shouting that he want it the throne so much that he was plotting and making all kind of schemes to get it, almost like a high treason.
And do you really think that his father, the father who always neglected him is going to support the marriage with his favorite?.
The really need to beat the queen and her family first.
Just came out as omega. Your mom will lose her claims, your father will support the marriage as it would only benefit the Rishars claims to the throne. And they stay together.
