The Fourth Imperial Princess, Cecilia, was shunned by her family and called the “Poison Princess.”

The only one who ever smiled kindly at her was her older sister, the Second Imperial Princess, Aaliyah.

…But that trust was shattered by the cruelest betrayal.

At Aaliyah’s command, Cecilia was captured and executed by the hand of her loyal knight, Daniel.

Betrayed by the sister she trusted, the moment death embraced Cecilia…time rewound.

Waking up again, she swore: “I will make that woman suffer the same hell I did.”

With vengeance in her heart, Cecilia visited the slave market, where a man chained in iron appeared before her…Daniel.

“I finally found you…”

She bought the man who had once killed her and coldly commanded, “Assist me in my revenge.”

Hatred, forgiveness, or perhaps…love?

The betrayed Imperial Princess and the Most Vicious Slave Knight who once killed her.

Bound by poison and chains, a dangerous yet beautiful master-and-servant romance begins now
