Question

I was wondering that what is yona trying to accomplish by going along with kye sook's plan, I mean I get that she wants to to protect the dragons but what after that, does she plan to stay in the castle forever just obeying kye sook? Does she plan to stay away from hak forever? I mean I know that that's not gonna happen because as the reader I know something will change the current situation however, I wanna know what the characters themselves are thinking.
