The Villainess’ Son is Innocent

I became the daughter of the heroine in a completed novel.
The original story was over, and I was living a happy life thanks to the buffs of having the heroine as a mother.
“Velsia. Only I will ever love everything about you.”
The son of a villainess who suffered from madness.
Emil Calixt, an innocent boy isolated due to the villainess’ sins.
Inheriting her madness, that boy slaughtered my family,
and upon my death, I returned to the age of ten.
So, in an attempt to avoid death
I tried to cure Emil’s madness…
“You are the only one who saw me for who I am.”
“…Emil, hold on just a moment.”
“You are the only one who reached out to me.”
However, that boy, whom I thought had grown better than anyone else…
“So, you are the only one who must remain by my side.”
Contrary to my intentions, he became obsessed with me.
“I… want you to keep pitying me.”
That little boy had grown into a man, and now he was clinging onto me.
