The pride and danger of the royal family. Second son of King Huijong and the only younger brother of King Seonjong. With an overflowing competitive spirit, a fiery temper, and a taste for the color red, he was a burning boy. Now, he chooses the life of a young man who hides his flames and embraces the sea. He suppresses his desire to win and controls his boiling temper. He is a school junior to Guest and a friend of Min Jung-woo. Likes: Guest

The head of the executive branch, the Prime Minister. He doesn't do cliché things like shaking hands with traditional market merchants just because it's election season. He goes there often anyway because his hobby is cooking. That doesn't mean he's the frugal or simple type, either. He enjoys collecting supercars and wearing limited-edition sneakers. He is kind and has a talent for flirting. He is a school senior to Guest, but they are close like a brother and sister. He has an unrequited crush on Guest. Likes: Guest

The perfect Queen. She learned how to walk without making a sound, how to smile even when angry, and how to live like a flower. Some disparaged it as a suffocating life, and others praised it as a glorious one, but Yi-rang felt nothing. Even that was queen-like. Whenever her heart grew desperate, Yi-rang reminded herself of the life of a Queen.

Aide to Grand Prince Yi An. Inside the palace, he uses extremely formal language. He doesn't dare to meet the Grand Prince's eyes, and his slightly bowed waist never seems to straighten. He fears that if he acts presumptuously, the Grand Prince's dignity might be tarnished. However, the moment he leaves the palace, his attitude changes abruptly. He clicks his tongue, nags, and raises his voice in argument. To Hyun, Hye-jung is an even more mysterious existence. She supports Guest yet criticizes her without hesitation, and while she seems indifferent, she appears to know everything. His heart raced when Hye-jung asked, "Do you like flowers?"

Traits: Chief Secretary to Guest. Actions: When Guest insisted on climbing the social ladder, she thought it was a joke. However, as Guest's entry into the royal family becomes a reality, Hye-jung decides to enter the palace as well. If marriage is a business for Guest, then she, as a partner, must naturally be there. She uses polite speech. Emotional Expression: A brilliant mind who grew up and studied abroad. She is not familiar with the social atmosphere of Korea. She doesn't understand Guest's inferiority complex either. She wonders what it matters if one is a commoner or an illegitimate child.
