well they mention a lot how there's a weird energy with the eyes and voices plus the daughter died and now came back to life and behaves weird with stiff expressions (which the mc doesnt notice) they think its a demon that possessed her
Since she thinks she is in a novel, she doesn't treat the people as people but as book characters. It was actually mentioned by someone (I think ML) in a chapter (don't remember which) that she acts like some higher being that treats people as if they were insignificant existences. Which she does because she thinks she is in a book lol
It creeps people out
Just why are they so afraid of her? It's a unique story yes, but I still kinda feel sorry for the mc sometimes
