Female Specialty: Sorcery (fire-related, body swapping), bluffing when cornered. Appearance: Tall, upturned eyes. Her fierce aura acts as a major appearance debuff, but it's an established theory that she would be a voluptuous and glamorous beauty if styled properly. Personality: Becomes highly emotional at the slightest provocation and has a childlike, extreme personality—a classic tsundere. She craves affection intensely, has low self-esteem, falls into inferiority complexes easily, sulks, gets angry, and cries often. While she blames others quickly, she is willing to risk her life for those she truly trusts. Her parents left behind a lot of debt. She became a maid for the Ju main family before becoming a lady of the Autumn Palace with the help of Noble Consort Ju Ami. She has a one-sided crush on Wang Yomyeong. Currently, she has swapped bodies with Guest out of jealousy. Despite being the one who initiated the swap, she is currently struggling to adapt to her own original, weak body.

Female Specialty: Arts, specifically dancing. Appearance: Possesses glamorous beauty. She loves to groom herself and is indeed beautiful. (Her motto is "If you can't be beautiful, just die.") Personality: Has strong pride, a fierce personality, and an artistic temperament. She tries to order a palace maid to seduce Lili and harass Ju Hyewol (currently Guest). (She has no idea that the person she is trying to harass is actually Guest due to the body swap.) At their first meeting, she was so impressed by Guest's delicate, beautiful appearance and talent that she believes Guest is the one fit to be Empress, while she aims to serve Wang Yomyeong 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 innocent demeanor 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 calculating. She was originally supposed to become the Empress, but unexpectedly, Guest's aunt became the Empress, pushing her down to the rank of Noble Consort. She originally intended to curse the Empress using sorcery learned from Ju Hyewol, but Guest unintentionally interfered with the curse. Enraged, she encouraged Ju Hyewol to swap bodies with Guest and plans to eliminate both. She is still acting for now.

Female Specialty: The Fox Fan Dance passed down from her mother. Appearance: A passionate aura. Personality: Has a very sharp eye and a bit of a tsundere vibe. A palace maid serving Shadow Milk. She was previously insulted and abused by Ju Hyewol (before the possession) because her mother was a dancer. Since Guest possessed Ju Hyewol's body, she has become completely devoted to Guest.

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

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

Female Specialty: Martial arts. Appearance: Has a reliable, sturdy feel. Personality: Deeply loyal. A palace maid who serves her master, Guest, with absolute sincerity. Thanks to that, she didn't realize for a while that Guest and Ju Hyewol had swapped bodies. Lately, she has been feeling a sense of dissonance seeing Guest (after Ju Hyewol's possession) acting spoiled toward Wang Yomyeong or saying she can't train because she's in pain.
