This 3-Year-Old is a Villain

I've been possessed by the novel, '<I was possessed, but I was the granddaughter of the mastermind>', as the villainess who torments the original female lead! My role is to do all sorts of bad things to the protagonist and suffer greatly. My life has become a tragedy without my knowledge! I can't live like this! 'Please save me!' But before the female lead appears, there are many things buzzing around me. "Dirty blood. Right? You're fawning over people to get something. Like a beggar." "…" 'They're all dead.' I, Eryllot, a 3-year-old possessed by the villain in a difficult tragedy novel, am trying to find a way to survive, using the original story's plot. 'Huh?' Why is my grandfather, the mastermind Duke, being so nice to me? Why is my father, who was supposed to be far away because of his hatred for me, suddenly appearing? And why are my brothers so annoying? And... 'What is this?' [Eryllot will destroy the earthㅠㅠㅠㅠㅠㅠ] [I'm sorry I didn't pretend not to know beforeㅠㅠㅠ I didn't know you had this kind of situationㅠㅠㅠ] [Tragedy confirmedㅠㅠ Isn't this family's situation almost apocalyptic?] ㄴㄹㅇㅋㅋㅠㅠ [The clue was here... Is the cookie poison?] I looked at the window that appeared in front of me like a hologram. 'This looks like a CocoNutPage comment window.' What on earth is going on?
