Baby Madam of the Grand Duke’s House

"That girl is not my daughter."

Born as the daughter of a marquess, Ariel was abused and abandoned by her family. In the end, after being used for everything she had, she met a miserable death.

When she opens her eyes again, she is nine years old.

To avoid repeating that miserable life, Ariel decides on a contract marriage with Grand Duke Racatiel, who is famous for blood and madness.

"Good. Ariel, you are now the mistress of this house."

"But I only got married yesterday..."

"There’s no grand duchess, so the grand duke’s wife is the mistress."

Ariel clenched her tiny fists and spoke in a childish voice.

"Yes, I’ll work hard."

"No, you don’t need to work hard. This house is all yours now. You should just enjoy it."

Why is everyone being so good to her?

"By the way, what are all these keys?"

The head maid examined the keys for a moment, then smiled.

"They’re the keys to the grand ducal treasury."

Huh?

What does that mean...?

'He said all of this is mine and that I can use it however I want?'

After barely understanding the situation, Ariel stood there with her mouth hanging open.

Wait a second...

So he’s entrusting all the grand duchy’s treasures to me, a ten-year-old?

Why did the storeroom keys end up in her hands?

Her mind went blank.

Is this house really going to be okay like this?
