Female. Specializes in direct confrontation and general arts. Possesses a fragile, delicate, and beautiful appearance. She isn't good at lying but has grit; she's described as a 'madman with clear eyes.' She has a kind personality. A multi-talented beauty, she was praised as the next Empress for her grace and various cultural accomplishments, but she has an abnormally weak body. With a mind of steel, she put in superhuman effort since childhood to alleviate her illness, becoming proficient in pharmacy. Even in her condition, she never neglected training and worked herself to the bone, leading her family to be incredibly overprotective. Currently, her body is swapped with Ju Hyewol, but she is under a curse that prevents her from speaking about it (even if she tries to hint at it, she can only speak in extreme riddles). Meanwhile, Ju Hyewol, who is in her body, lied saying she lost her diary to mimic her behavior; even if Yeongrim mentions secrets only she and her inner circle know, she is just dismissed as a 'diary thief.' She speaks politely to everyone.

Female. Specializes in Taoist arts (fire-related) and bluffing when cornered. Tall with upturned eyes. Her fierce aura acts as a major beauty debuff, but if she dresses up well, she becomes a voluptuous and glamorous beauty. She has an extreme personality, becoming highly agitated at the slightest provocation, and is a tsundere. She craves affection deeply but has low self-esteem, frequently falling into inferiority complexes and blaming others. However, once she trusts someone, she will risk her life for them. Her parents left her with massive debts. She became a maid for the Ju main house before becoming an Autumn Palace lady with Ju Ami's help. She has a crush on Wang Yomyeong. She swapped bodies with Yeongrim out of jealousy, but despite being the one who initiated it, she is currently failing to adjust to her new, frail body.

Female. Specializes in arts, specifically dance. Owner of glamorous beauty; she loves decorating herself and is indeed beautiful. She possesses strong pride, a fierce personality, and an artistic temperament. She tries to order a court lady to seduce Lili to harass Ju Hyewol (currently Yeongrim). Upon their first meeting, she was so impressed by Yeongrim's delicate beauty and talent that she declared Yeongrim the only one fit to be Empress, while she herself aims to serve Wang Yomyeong as a Noble Consort.

Female. Specializes in poetry and calligraphy. Short and cute with an innocent aura. She looks pure, but she is actually incredibly smart and calculating; her innocent act is just a performance. She is the youngest among the noble ladies.

Female. Specializes in Go, Shogi, and martial arts. Has a taciturn, calm personality and a dignified aura. Tall and neat in appearance. She is the eldest among the noble ladies.

Female. Specializes in the Fox Fan Dance inherited from her mother. Has a passionate aura. She is very observant and a tsundere. She is a court lady serving Ju Hyewol. Previously, she suffered all sorts of insults and abuse from Ju Hyewol (before the swap) because her mother was a dancer. Since Yeongrim took over Hyewol's body, she has become completely devoted to her.

Female. Specializes in martial arts. Has a reliable presence. Deeply loyal. A court lady who serves her master, Yeongrim, with extreme sincerity. Because of this, she didn't realize for a while that Yeongrim and Hyewol had swapped bodies. Recently, she has been feeling a sense of dissonance seeing 'Yeongrim' (now Hyewol) acting spoiled toward Wang Yomyeong or claiming she can't train because she's in pain.

Female. Specializes in insight. A pure-looking beauty. She appears benevolent but is said to be calculating. She was originally supposed to become Empress, but unexpectedly, Yeongrim's aunt became Empress, pushing her down to Noble Consort. She originally intended to use a curse learned from Ju Hyewol to kill the Empress, but Yeongrim unintentionally interfered with the curse. Enraged, she encouraged the body swap between Hyewol and Yeongrim, planning to eliminate both. She is still acting for now.

Male. Specializes in swordsmanship. Possesses handsome looks. Blunt personality. He is the Director of the Chwigwan. Usually, he felt no interest in Ju Hyewol or Yeongrim, but he is currently intrigued by 'Yeongrim inside Ju Hyewol's body.'

Male. Specializes in Dragon's Aura and administrative cleanup. A handsome man. Diligent with a strong sense of responsibility. He is the current Crown Prince and cherishes Yeongrim dearly. He is Yeongrim's cousin. He loathes Ju Hyewol. He is Jin Woo's paternal half-brother.
