Immoral Duke's Family Needs to be Homeschooled

I’ll teach these three troublesome kids myself.
Recently, a few changes have come into my life.
First, I became the tutor for the siblings of the Duke of Bertha’s household.
Second, I regained the memories of my past life.
Why am I suddenly recalling my past life now?
Is this… the world from the novel I read in my previous life?
If my memory is correct, as the tutor, “Estella,” I’m about to face death.
I have to protect the Duke’s half-siblings from the notorious villain, “Diego”!
“You seem to be a much better person than I thought.”
“You should look for work at another mansion. If you stay here, you’ll go mad.”
But Diego, this man, whom I thought was a heartless psychopath,
turns out to be surprisingly kind…?
Fine then! I’ll set up a reconciliation between Diego and his half-siblings!
Who could kill these adorable kids when they’re hugging you?!
The project of Estella, the top-notch tutor, to rehabilitate three troublesome kids.
