This absolute Beabicth. I bet Vivien was never going to be queen anyway, I'm guessing she would be killed cuz she was the original antagonist in the novel.
This seems to be a good first few chapters as introduction, I guess the espionage and intrigue would come in later chapters. Still, the tension is somewhat lacking, but it's rare to see a timid MC standing up to a demon this quickly; as for whether this is good kind of rare or bad kind of rare...
