I Became the Villain's Lost Daughter

I possessed an extra who didn’t even have a name in the novel. Her features are black hair and purple eyes that means that she is cursed. And I’m the lost daughter of the villain in the novel?! I thought I was a passing by extra, but she was actually the lost daughter of the villainous Grand Duke.

*“Erita, my beloved daughter.”

“My precious little sister. I’ll protect you.”*

……are these the bloody villains I’ve seen? My father and brother, who people said to be cruel, were too sweet to me. But the villain has a death ending! It was the first time I received love and warmth, and I decided to change the cruel ending of my friendly family since I possessed it 10 years earlier than the original. Yeah, I will definitely change my family’s future……

“Erita, I love you.”

What’s wrong with the Male Lead?
