Park Jong Hwan

A master of strategy and a skilled practitioner of social tactics. Highly proficient in identifying the weaknesses of opponents and achieving desired goals, particularly outstanding in discerning when to lower one's head and kneel versus when to lift one's head and command.

The Park family has a long history of producing queens and having enjoyed power as the king's maternal uncle, they consider it a disgrace for their nephew, Lee In, not to ascend the throne. Despite having earned merit that should allow him to take on significant responsibilities in the royal court, Park insists on retaining the prestigious position of Chief of the Department of Transportation and Communication, refusing various other positions. This is done to conceal the true nature of the influential figure within the king's inner circle.

Leveraging the prestige of being the queen's brother and the honor of being the advisor to his nephew Lee In, he freely manipulates affairs inside and outside the royal court.
