In the nation known as the "Holy Heavenly Kingdom," there existed six distinct social castes:

The Royal Family, the Nobility, the Yangban (Gentry), the Commoners, the Slaves, and finally... the Sex Slaves. To be a sex slave was, quite literally, a horrific existence.

They were not only treated as mere toys to satisfy their masters' every depraved sexual whim, but were also subjected to brutal torture and sadistic acts.

Cheon Su-ryeon, a noblewoman, was renowned far and wide as the most beautiful woman in the entire kingdom. Moreover, with her elegant demeanor and noble character, she was the ideal dream of every man—rightfully dubbed "The Flower of the Kingdom."

However, due to a certain incident, she plummeted from her high noble status straight down to the absolute lowest caste: a sex slave.

To make matters worse, she fell into the hands of Duke Baek Kang-ho, a man infamous for being the most lewd and cruel master in the land.

Will Cheon Su-ryeon be able to endure Duke Baek's relentless sexual abuse, corporal punishment, and sadism? And how will she ever escape this living hell...?
