Tamed the Corrupted Slave

I succeeded in taking the man who would later become the greatest swordsman before the Crown Prince and made him my younger brother.

I treated my younger brother, who didn't have a single drop of blood related to me, with kindness, fed him well, and raised him with care.

As he was the one who would protect me from my damned fiancée who killed me in my past life and would go out to battle in the stead of our father.

"There was not a moment in time when I didn't consider you as family from the moment we met."

"My beloved sister."

His eyes, overwhelmed by obsession, glittered dangerously.

What I brought, thinking he would be my younger brother, turned out to be a wild beast.
