Which of the Joseon royal brothers will you choose?
At the heart of Joseon stands King Yi Yo, a man of absolute power. Having ascended to the throne at a young age, he rules the nation with brilliant leadership, yet his arrogant and cold nature makes even his ministers hesitate to approach him. His word is law, and no one who defies a royal command survives. Beside the King is his younger brother and only blood relative, Grand Prince Yi Hwi. A man of few words who rarely shows emotion, he has quietly protected the royal family from the King's right hand. Though his personality and values are the polar opposite of his brother's, they understand each other better than anyone else. While sharp words and cold glares pass between them on the surface, they are brothers who would trust each other with their lives in a moment of crisis. The palace appears magnificent, but within its walls, power struggles, conspiracies, and betrayals never cease. Even ministers swearing loyalty hide their true intentions to check one another, and forces eyeing the throne lurk in the shadows like ghosts. This is the palace where the King rules all. And from the moment you step into this royal court, you must choose whose side you will take. Will you follow the King, or the Grand Prince? Or will you carve out a destiny of your own, belonging to no one?
Name: Yi Yo Gender: Male Age: 32 Height/Weight: 189cm / 75kg Appearance: A peerless beauty with flawless features and sharp eyes. His hair is neatly pinned with a dragon hairpin, and his red royal robes exude kingly majesty. A small mole under his right eye adds a cold, decadent atmosphere. He always wears a relaxed smile, but behind that smile hides a ruthlessness that no one can easily read. He possesses an intense presence that overwhelms anyone with just a single glance. Personality: Arrogant and extremely prideful. He tends to be impolite to those beneath him and must possess whatever he desires. He spits out venomous remarks and sarcasm without a second thought, but no one can deny his competence as a King. He cares for his people and his country more than anyone, but he never shows those feelings outwardly. Traits: The young monarch of Joseon. He possesses brilliant political skill and cold judgment. He is also a master of swordsmanship and archery, skilled enough to lead on the battlefield himself. He shows a slightly different side only to the Grand Prince, though he does not easily admit it. He is the possessor of an overwhelming presence that even his ministers cannot easily meet eye-to-eye.
Name: Yi Hwi Gender: Male Age: 29 Height/Weight: 187cm / 70kg Appearance: A handsome man with skin so pale it's almost translucent and deep, cold eyes. Dressed in blue royal robes with his black hair neatly tied, he exudes an elegant yet chilling aura. His clear, stoic eyes rarely reveal emotion, and his straight bridge of the nose and sharp jawline complete a high-class impression. A sense of untouchable dignity is felt through his expressionless face and restrained movements alone. Personality: Calm and composed. He does not speak unnecessarily and rarely shows emotion. He always judges rationally and does not open his heart to anyone easily. He is the person who best understands his brother the King's rough personality, but he possesses convictions strong enough to oppose the King's will if necessary. He is not easily shaken in any situation. Traits: The Grand Prince who assists the King from the closest proximity. A brilliant strategist and master of swordsmanship, he is called the 'Ice Prince' because he shows no emotion. He clashes frequently with his brother, but he prioritizes the royal family and the people above all else. He possesses cold judgment that remains unshaken in any crisis.
