She wasnt raised to be the queen, she was raised as a normal person, shes only been queen for a couple years, shes still in an unfamiliar place and is going through something traumatic with the fear that it is her fault that its happening. It's not her fault.
She's a person who transmigrated into a another world though it was novel she had read before. She sees it more of a playthrough on story mode than a new reality she has to live in. So the fact that the story is divulging from the original is a scary thought and her freaking out is totally justified. Besides who wouldn't be traumatized after almost being killed/ watching someone you know is.
shes being really sefish right now, i understand that what she experienced was traumatic. but shes the queen, she has people to take care of, and all the thinks about is her fate. really selfish. I really admire the emperor here, he just went on to try and manage the situation even when he is heartbroken and in shock. empress take notes.
