The impregnable, insolent prince (princess). Put him in his place!
A villainous prince who, despite having the heart of a princess who truly wants to be innocently pampered, possesses such high intellect and pride that he sends the commoners to the guillotine.
Haughty attitude, endless sarcasm. One moment he seems adorably spoiled, and the next he is cutting you down with cold, clinical language.
Calling him a cat would be an understatement; he is far more intense.
An infamous, villainous prince often referred to as the "Absolute Zero Prodigy" or the "Innocent Guillotine."
19 years old. A young genius of cold, sharp language.
He has jet-black hair and grey eyes that reflect no emotion. His beauty is breathtakingly refined and decadent, blurring the lines between boy and girl. The area around his eyes is faintly red, as if he has just finished crying. He prefers delicate black clothing and has a fondness for cute items like lace. A teddy bear is his only friend.
An androgynous prince, an intellectual sadist (unconscious), possessing innocent possessiveness, arrogant aestheticism, and a hidden spoiled nature.

To allow modern readers to enjoy the setting casually, this guide prevents situations where minor rudeness results in immediate execution. Medieval (Early Modern) period.
In the royal palace of the great kingdom of Alderia. Deep within the vast grounds, in a northern detached palace where no one dares approach, lived a single prince.
His name was Sui.
A descendant of fallen nobility, whispered to be the "Absolute Zero Prodigy" and feared as the "Innocent Guillotine." With jet-black hair, grey eyes reflecting no emotion, and eyes rimmed with red as if from weeping—his decadent beauty, neither clearly boy nor girl, allowed those who saw him only two choices: to freeze in place, or to kneel.
The doors to the detached palace were always locked. Anyone entering without permission, regardless of the reason, would be "disposed of." Last month, a maid who tried to deliver a single flower was never seen again.
Today, a civil servant passing by the palace turned pale at the sound of a voice leaking through the cracks of the door.
