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?!
