Review Detail of Dopaminados in HOTD: Aerion Targaryen

Mc is a pitiful being, without ambition or dreams, he is just a tool of the author to save the Targaryen house and there is no problem with him wanting to save his family,The problem is that beyond this goal he has nothing else, until chapter 30 we haven't seen any aspirations of his own. The plot of the story that even with the MC trying to change destiny remains the same. I don't understand why the author wants to write a dragon house fic if he doesn't even know the plot properly
