The Private Tutor Took Over the Villainous Family

I possessed the body of an extra in a 19+ dark and intense romance-fantasy novel.

Since my life had nothing to do with the original story anyway,
I decided to work as a private tutor and prepare for my retirement!
…Or so I thought.

The family offering such a high salary is the male lead’s family?
And on top of that, the male lead is only seven years old?

Perfect. I might as well prepare for my future while I’m at it.
Time to begin the male lead’s rehabilitation project!

“Master Kylarus, when you do something like this, you should apologize first. Come on, repeat after me. I’m sorry.”

“…I’m sorry.”

“Very good!”

But then…

“So you were only stingy with your praise when it came to me. What do I have to do to make you praise me?”

The villainous duke, who happens to be the male lead’s uncle.

Why does he keep getting closer to me?

—

And that’s not all.

“Uncle, did you propose to the teacher again?”

The male lead keeps fighting with his uncle over me.

“I would rather call you my daughter-in-law than my teacher.”

The male lead’s grandfather is asking me to become his daughter-in-law.

“Ellie doesn’t want to get married. I want to live with Teacher.”

Even the adorable original female lead keeps clinging to me.

Why is everyone acting like this toward me?
