Yona did have an alternative: she could have refused the throne.
She was not being compelled by a law of nature, an irresistible prophecy, or an assembly crowning her at spearpoint.
“I do not want the throne under these conditions.”
“I will not govern by relying on the same men who tried to kill me.”
“I will not accept a crown handed to me by the man behind the coup without a clear transition, an investigation, or any conditions.”
But she accepted it. From that moment on, she cannot be presented as someone with no options who was simply swept along by circumstances. She chose to enter that structure.
Even after accepting the throne, Yona still had alternatives. She could have dismissed Kye-sook. She could have refused to keep Su-Won as an adviser. She could have replaced those involved in the coup and formed her own government.
That would have meant actually exercising power. But she would also have needed her own competent people, administrative knowledge, a political network, experience, and a transition plan. She had none of those things.
Then it would have become obvious that Yona was not prepared to govern without relying on Su-Won’s political and administrative machinery.
A kingdom does not remain standing because its queen stares intensely at the reports until they arrange themselves.
So it is not true that she “had no choice.” She had choices, but the alternatives would have exposed her lack of capacity:
Refuse the throne, and give up the ending the narrative wanted for her.
Accept the throne and purge the court, risking serious collapse because she had no competent replacements.
Accept the throne and keep Kye-sook and Su-Won, allowing the kingdom to function while undermining any claim to genuine independence.
Agency does not mean having a comfortable option. It means choosing between difficult alternatives and accepting the consequences.
Yona chose the third option. It may have been pragmatic. It may even have been the least harmful option. But it was still a choice, and it should be called what it was: Yona inherited the crown, but she also inherited Su-Won’s government, including his officials and his knowledge.
She did not build a government of her own. She placed herself at the top of the existing one.
Which makes the idea that everyone now depends on Yona’s extraordinary political ability rather amusing. If she dismissed the administrator and rejected the former king as her adviser, she would probably be left without a kingdom within two days, and without any subjects capable of appreciating how incredibly “fortunate” they are to have her as queen.
The crown is hers. The machinery of government still belongs to them.
