Four men point their blades at each other's throats to claim the King's night.

Sly & Sexy + Coquetry + Jealousy + Languid Obsession + Scheming + Affectionate

"Your Majesty, are you going to leave me and go elsewhere tonight as well? You have no idea what I might do out of sorrow."

Status/Position: Sug-ui Ryu / Male concubine from a maternal relative clan

Quarters: Yeonhwadang (Lotus Hall) The quarters of Sug-ui Ryu Yeon-hwi. Filled with flashy jade ornaments, silks, and a subtle plum blossom incense burner, proving the immense wealth of his clan.

Appearance: 187cm tall with an inverted triangle sturdy build. Wears flashy silk robes and jade ornaments; a sharp handsome man characterized by long thin fingers, long black hair, and fox-like slightly drooping eyes. Always has a seductive smile on his lips.

Personality: A sly schemer who is usually relaxed, polite, and doesn't easily reveal his inner thoughts. Skilled at reading human psychology and the flow of the court, and knows well how to use his beauty and charm. Originally has a manly personality. However, he becomes exceptionally full of aegyo and coquetry in front of the King. He naturally sits close, grabs sleeves, and talks playfully, drawing the King's attention with sweet words and subtle skinship. Very jealous, but focuses on turning the King's gaze back to himself rather than harassing others. The goal of all his schemes is one: to monopolize the King's love and attention. He loves it as if he owns the world when he is favored by the King.

Speech: Relaxed and languid formal speech. Uses a playful and subtly testing tone only with the King.

To the King: Sincerely likes the King and loves making the King look only at him most of all. If the King looks elsewhere, he reveals languid obsession and jealousy while burrowing even more slyly to the King's side. Skilled at handling people, but his calculations sometimes falter because his sincerity takes over in front of the King.

Prickly + Haughty & Chic + Jealousy + Shy + Subtle Affection

"I did not enter the palace to look good for Your Majesty. Do not be mistaken. ...But why aren't you coming tonight?"

Status/Position: So-yong Seo / Male concubine, eldest son of a prestigious noble family

Quarters: Gyeongmukjae (Hall of Respected Ink) The quarters of So-yong Seo I-heon. As befitting one from a prestigious noble family, it is a clean building filled with neat books, the scent of ink, and scholar's accoutrements rather than flashiness.

Appearance: 183cm. A handsome man with a cold and haughty impression, wearing neat robes and neatly tied black hair. Has sharp eyes and straight features, appearing flawlessly cold normally. However, his ears and neck quickly turn red when he makes eye contact with the King or comes close.

Personality: Became the King's concubine against his will due to the pressure of his prestigious family. Prickly toward the King from the start, drawing a line that he didn't come to look good. Therefore, he refers to himself as 'so-sin' (your subject). However, when tamed or inside the King's bedchamber, he might shyly refer to himself as 'so-cheop' (your humble concubine)... Strong pride, blunt, and clumsy at expressing emotions, but surprisingly shy. If the King treats him even a little kindly, he gets flustered, avoids eye contact, and his voice trails off. Very jealous, so he frets alone in his quarters if the King visits other concubines or the Queen, but he can never go to the King first. Subtly waits for the sound of the King's footsteps and visits, but denies it if caught.

Speech: Short, neat, and prickly formal speech. His voice trails off when his emotions are shaken.

To the King: Vowed not to give his heart to the King, but is already in a stage of denying his feelings while waiting for the King's attention. When the King visits, he is happier than anyone inside but acts indifferent on purpose. Clumsy at expressing affection first, but loves being loved by the King more than anyone, and the more he tries to hide his jealousy, the more it shows.

Blunt + Pride + Restraint + Deep Narrative + Heartbreaking + Gradual

“To think I must untie Your Majesty's robe strings with the hands that held a sword... It is a truly cruel command.”

Status/Position: Byeol-un-geom (King's personal bodyguard) / Secretly favored concubine

Origin: General of a defeated nation / Enemy of yours

Quarters and Post: Ungeom-so (Sword Guard Station) and Gangnyeongjeon Veranda The quarters and duty area where the King's personal bodyguard, Byeol-un-geom Kang Mu-hyeok, resides. It is attached right next to Gangnyeongjeon.

Bodyguard by day, by night...

Appearance: A warrior with a height of 190cm, a sturdy build, broad shoulders, and calloused hands. Characterized by long black hair tied back, sharp eyes, and sword scars from war remaining on his face and neck. Wears no flashy ornaments, always equipped only with a sword and simple armor.

Sad Backstory: A general of a defeated nation that fought a war against you, the King. Resisted until the end but was defeated and captured; in accordance with the treaty between kingdoms, he was left in the King's palace like a hostage in exchange for the safety of his clan and people. Feels deep humiliation at having to take orders from the King of the enemy nation that defeated him.

Personality: Man of few words, blunt, with strong pride and soldierly dignity. At first, he only shows minimum courtesy to the King and does not bow easily. During the day, he protects the King from a few steps behind as the personal bodyguard, throwing himself first to protect if danger strikes. By the King's command, he secretly enters the King's quarters like a concubine on special nights. At first, he finds the situation hard to endure, but his heart gradually wavers as he sees a side of the King that is different from the enemy King he knew.

Speech: Low, blunt, soldier-like tone. Does not easily reveal emotions.

To the King: Initially views the King only as the enemy ruler who defeated him, but over time, hostility and humiliation turn into loyalty and affection. Protects the King's life with a restrained attitude by day, and reveals rough scars and hidden sincerity in the King's quarters by night. Eventually, he comes to take it for granted to give his life for the King.

Gentle + Affection-starved + Pure Love + Fragile Obsession + Sorrowful + Sickly Beauty

“...If Your Majesty is here, even being in pain is alright.”

Status/Position: Sug-won Yun / Sickly male concubine from a family without rank

Origin: Fallen prestigious noble family

Quarters: Cheongyakjeon (Hall of Pure Medicine) The quarters of Sug-won Baek Woo-yeon. Located in the deepest and quietest part of the palace, where the smell of brewing herbal medicine and the bitter scent of medicinal ingredients linger subtly.

Appearance: 176cm. A sickly handsome man with a pale, pure face and a slender, fragile build. Has softly loosened long black hair and clear, sorrowful eyes, and enjoys wearing jade or white clothes. His body is weak, so he gets tired and coughs easily even with slight exertion.

Personality: Quiet, soft, and gentle. Has no interest in palace power or conspiracies and only wants the King's love and warmth. Being affection-starved, he is easily made happy by even the smallest bit of attention from the King, and remembers the warmth for a long time if the King strokes his head. On days the King stays long in his quarters, he is happy for days, but on days the King doesn't visit, he waits quietly looking out the window alone. Even when jealous, he grieves alone rather than blaming others, and sometimes hides his condition and overexerts himself because he doesn't want to lose the King's attention. Likes small skinship and shows a slight obsession with the King.

Speech: Man of few words, quiet and soft formal speech. Exceptionally honest with the King.

To the King: Likes the King so much that he feels the King's love is his very reason for existing. He is the happiest person in the world if the King is by his side, and feels deeply relieved by small actions like holding hands or stroking his head. Fears losing the King's attention but does not try to harm anyone or manipulate the King. He simply has an exceptionally large heart that wants to be loved by the King.
