This 3-Year-Old Is a Villainess

I possessed the original female lead of the possession novel called [I Possessed The Villain’s Granddaughter]. That is, the villainess who torments the real female lead! What did you say? It’s a villainess role that greatly suffers after doing all kinds of bad things to the main character?! Before I knew it, the genre of my life became a tragedy! I can’t live like this! However, before the female lead could even appear, there were already all sorts of events happening in front of me. Why was my Grandfather, the Villainous Grand Duke, so kind to me? And, why did my Father suddenly appear even though he was hated by Grandfather and had always been away? Also, why are my older brothers acting so annoying? Moreover. I stared at the window that floated in front of me like a hologram. How the hell did it become like this!? Source: NU
