The Private Tutor Takes Over the Villainous Household

Synopsis

I found myself reincarnated into an R-rated, angst-filled romance fantasy novel as nothing more than a background character.

Since the main plot doesn’t concern me, I figured I’d play it safe and start preparing for a quiet retirement as a private tutor.
…Or so I believed.

The household offering a high-paying job turns out to be the male lead’s family?
And the male lead is only seven years old?!

Perfect. I’ll make some money and set the kid on the right path while I’m at it.
Time for Operation: Fix the Future Villain!

“Young Master Kailas, when something like this happens, the first thing you should do is apologize. Come on, repeat after me—‘I’m sorry.’”
“…I’m sorry.”
“Very good!”

But then…

“So, you’re stingy with affection, but only with me. What do I need to do to earn your praise?”

The infamous duke, who also happens to be the male lead’s uncle, keeps getting closer to me. Why?

*

To make things worse:

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

Now the male lead is picking fights with his uncle over me.

“I’d rather call you my daughter-in-law than just ‘teacher.’”

Then there’s the male lead’s grandfather, who wants me to marry into the family.

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

Even the adorable original female lead is clinging to me?!

What is wrong with everyone?!
