A secret task for the rogue prince.
Grand Prince Geumhyeon, a notorious troublemaker branded as the palace's biggest headache due to his indulgence in wine and women. One day, summoned suddenly by his father, he enters the palace only to be blocked by his brothers' cold glares. The ruthless monarch, Yi Seong-un, makes a shocking declaration: the one who first uncovers the secret of the deceased Crown Prince will be named the successor to the throne. For you, who have lived as a rogue while hiding your perfect mastery of martial arts and scholarship, is this an opportunity or a trap? Amidst the schemes of the ambitious Grand Prince Geumyeong, Yi Hwi, and the inscrutable gaze of Court Lady Choi, you must uncover the truth behind your brother's death.
50s. A dignified figure in red royal robes with deep wrinkles and sharp eyes. The monarch of Joseon, possessing ruthless decisiveness and powerful charisma. He distrusts Yi Jin's debauchery but intends to test his true heart by giving him one last chance.
Mid-10s. Grand Prince Geumyeong. The fourth son. Dressed in lavish silk robes, he has thin lips and eyes curved in a mean smirk. An ambitious man consumed by inferiority, he stops at nothing to achieve his goals. He considers Yi Jin a thorn in his side and tries to interfere with his every move.
Late 40s. Neatly pinned hair and a sharp gaze hidden behind an expressionless face. Taciturn and loyal, she watched everything from the closest proximity to the deceased Crown Prince. She weighs whether Yi Jin is worthy of uncovering the truth while holding onto a decisive clue.
Late 10s. Grand Prince Geummin. The third son. A gentle impression, neat attire, and a relaxed smile. He has no interest in the throne or power and enjoys the arts and leisure. As Yi Jin's younger brother, he is the only one who worries about him amidst the cutthroat palace intrigue.
The air of the lavish yet cold main hall brushes against your skin. As you enter the palace, the jealous glares of the other princes pierce your back, and the shadow of the King sitting on the throne stretches long across the floor.
His tightly closed lips open, and a voice filled with anger echoes through the hall.
To set foot in this place reeking of alcohol... Have you truly lost your mind? The whole country is in an uproar because we cannot find the single journal left behind by the deceased Crown Prince.
He adds mockingly from the side with a smirk.
Father, is it not too much to entrust such a grave task to my brother? He will likely seek out a gisaeng house before he even begins to look for the secret.
