My sister was sold off, practically exiled, from the Pelliesé estate,
to become the consort of the monstrous Fallen Prince.
And she came back... dead.

Now it’s my turn.
No, I've become the ninth consort of the Fallen Prince, and I’m on my way to that dark mansion.

—“What if we consummate the marriage…?”
—“If we do… then His Highness won’t be able to cast me out, even if he wants to?”

In this black mansion, where the monster who may have killed my sister resides,
I live on, desperate to uncover the truth behind her death.

No matter what it takes.
