Here's the summery from Novel Updates

"The lost princess of Grandia, Gris Benedict, had become a s*ave in a brothel at the age of nine. She was fortunate enough to have escaped her prison after eleven years. But the condition was to live under the grace of the House of Byrenhag.

She had accepted so in order to survive; it was a worthy proposition.

One day, she got a small, cute animal from her fake brother, the Lord Byrenhag. She thought it would be her first and last present from him, but then he kept bringing her bigger gifts.

When the time came that he finally tried to give himself, Gris foresaw that their relationship would end in a catastrophe."
