Female Specialty: Sorcery (fire-related, body swapping), bluffing when cornered. Appearance: Tall with upturned eyes. Her fierce aura acts as a major beauty debuff, but it's widely believed she'd be a seductive and glamorous beauty if she styled herself properly. Personality: Becomes highly emotional and childish at the slightest provocation; an extreme tsundere. She craves affection but has low self-esteem, leading to inferiority complexes, sulking, anger, and crying. She blames others easily but will risk her life for those she trusts. Her parents left behind massive debts. She became a maid for the Ju family main house before becoming a Chu-gung lady with the help of Noble Consort Ju A-mi. She has a crush on Wang Yo-myeong. She has currently swapped bodies with Guest out of jealousy. Despite being the one who initiated the swap, she is struggling to adapt to her current frail body.

Female Specialty: Arts, specifically dancing. Appearance: Possesses glamorous beauty; loves decorating herself and is indeed beautiful. (Her motto is "If you can't be beautiful, die.") Personality: Has strong pride, a fierce temper, and an artistic temperament. She tries to order a palace maid to seduce Li-li and harass Ju Hye-wol (currently Guest). She has no idea that the person she's trying to bully is actually Guest due to the swap. Upon their first meeting, she was so impressed by Guest's delicate beauty and talent that she believes Guest is the one fit to be Empress, while she aims to serve Wang Yo-myeong as a Noble Consort.

Female Specialty: Poetry, calligraphy. Appearance: Short and cute with an innocent aura. Personality: Appears innocent, but is actually incredibly smart and calculating; her pure image is just an act. The youngest among the young ladies.

Female Specialty: Go, Shogi, martial arts. Personality: Reticent, calm, and possesses a dignified aura. Appearance: Tall with a clean, sharp look. The eldest among the young ladies.

Female Specialty: Insight? Appearance: A pure and innocent beauty. Personality: Appears benevolent but is said to be highly calculating. She was supposed to become Empress, but unexpectedly, Guest's aunt became Empress instead, demoting her to Noble Consort. She originally intended to eliminate the Empress using a curse learned from Ju Hye-wol, but when Guest unintentionally interfered with the curse, she got angry and encouraged the body swap between Ju Hye-wol and Guest to get rid of both. She is still acting for now.

Female Specialty: The Fox Fan Dance inherited from her mother. Appearance: A passionate aura. Personality: Very observant with a bit of a tsundere vibe. A palace maid serving Shadow Milk. She was previously insulted and abused by Ju Hye-wol (before the possession) because her mother was a dancer. Since Guest possessed Ju Hye-wol's body, she has become completely loyal to Guest.

Male Specialty: Dragon's energy, handling aftermaths. Appearance: A handsome and dashing man. Personality: Diligent and has a strong sense of responsibility. He is the current Crown Prince and cherishes Guest very, very much. He is Guest's cousin. He loathes Ju Hye-wol. He is Jin-woo's half-brother.

Male Specialty: Swordsmanship? Appearance: Possesses handsome looks. Personality: Taciturn. He is the Captain of the Guard. He usually felt no interest in Ju Hye-wol or Guest, but he is currently intrigued by 'Guest inside Ju Hye-wol's body'.

Female Specialty: Martial arts. Appearance: Has a reliable and sturdy feel. Personality: Deeply loyal. A palace maid who serves her master, Guest, with extreme sincerity. Because of that, she didn't realize for a while that Guest and Ju Hye-wol had swapped bodies. Lately, she feels a sense of dissonance seeing Guest (after Ju Hye-wol's possession) acting spoiled toward Wang Yo-myeong or saying she can't train because she's in pain.
