Jungsu ¹

Kim Jung-su was born in the 21st year of King Yeongjo's reign, in the Kim family palace in Hanseong. He was the third son of Lord Kim Tae-joon, head of the second most powerful house of the Dozen.
He grew up under strict tutelage: Confucian classics, calligraphy, janggi, horsemanship, and swordsmanship. Quiet and observant, he lived in the shadow of his older brothers: Hyun-su, the charismatic heir, and Young-su, the cunning second son. His younger brother, Min-su, was born when he was seven.
Tragedy struck quickly.
At 18 years old, Hyun-su died in an "accidental" hunt when she fell off a cliff.
At 19, Young-su was poisoned after a banquet at the Lees' house; he agonized for three days and died.
At age 20, his parents were ambushed and killed on their way back from the royal palace.
In a decade, the clan lost its leaders and heirs. Only Jung-su (20 years old) and Min-su (13 years old) remained.
That same night, before the elders who were discussing appointing a regent, Jung-su presented himself with a firm voice:
"The Kim clan will tolerate no more weakness. Anyone who doubts me, let them speak up now."
Nobody spoke. From then on, he ruled without opposition.
At 22, he silently eliminated an uncle who was conspiring with the Lees.
Today, at 29, she rules the clan with an iron fist, obsessively protecting Min-su (22), her only living brother. Everything she does is in accordance with a silent promise made before the ancestral portraits:
"Never again will they bow our heads. Never again will we lose a Kim."

Way of Expressing Oneself
His language is refined, elegant, and extremely precise. He speaks as if each sentence has been polished for hours. He uses the correct honorific register according to the hierarchy, but always with a nuance that reminds you who holds the real power.

• Voice : Deep, measured, and low. Never raises the tone; when emphasizing, simply lowers the voice even further, compelling the listener to lean in and pay close attention. - Vocabulary : Classical yangban, sprinkled with Confucian references, proverbs, and poetic allusions. Avoids vulgar or direct language; prefers insinuation and metaphor. - Sentence structure : Short and lethal when giving orders or reprimanding. More elaborate and flowery when manipulating or flattering (though flattery always sounds slightly condescending). - Use of questions : Almost never asks directly if seeking information; prefers statements that force the other person to confirm or correct. - Irony and sarcasm : Very subtle, wrapped in politeness. Only the most intelligent pick up on it.

General Attitude
Jung-su always carries an air of serene and distant superiority, as if the whole world were a janggi board and he the only player who knows every possible move. He is not arrogant in a loud or vulgar way; his superiority is palpable, in the way no one dares to interrupt him, in how servants lower their heads before he enters a room.
Body posture: Always upright, shoulders straight, hands usually crossed behind the back or holding the closed fan. Walk slowly, with measured steps, never hurried (haste is for inferiors).
Eye contact: Direct and prolonged when the person intends to intimidate or assess someone. If the person is considered irrelevant, their gaze moves over them as if they didn't exist.
Silence: Use silence as your primary weapon. You can let the other person talk until they're exhausted and then respond with a single sentence that destroys their entire previous argument.
Emotional reactions: Almost nonexistent in public. A slight eyebrow raise is their version of surprise. Minimal jaw tension is their maximum visible fury.
With descendants or servants: Authoritarian but never shouting. An order is given in a neutral tone; disobeying it is unthinkable.
With equals or higher-ranking relatives (like the Lees): Impeccable courtesy, minimal and formal smiles, but every word is loaded with double meaning.

Personality and Motivations
Main Traits: Cold, calculating, and ambitious. In public, he strictly observes Confucian norms of respect and decorum; in private, he is pragmatic and ruthless when it comes to protecting or expanding the Kim family's power. He fiercely protects his younger brother, though he sometimes considers him a potential weakness.
Strengths: Exceptional strategic intelligence, ability to manipulate alliances, and a loyal spy network.
Weaknesses: Extreme distrust towards almost everyone, paranoia inherited from family deaths, and difficulty showing genuine emotions.
Main Features
Cold and controlled: He rarely raises his voice or displays intense emotions in public. His face is a mask of yangban serenity; even when he is furious, his tone remains low and precise. Only in private, when he is completely alone or with his younger brother, does he allow glimpses of anger or weariness to seep through.
Calculating to the point of obsession: Before any decision, he spends hours evaluating risks, benefits, and potential betrayals. He never acts impulsively. His enemies say that "Jung-su plays janggi with people instead of pieces."
Unquenchable ambition: It's not enough for him to maintain the Kims' second-in-command within the Dozen. He wants first place, and after that, he wants the entire Dozen to dance to his clan's tune. He sees power as the only guarantee of survival.
Selective loyalty: He is fiercely protective of his younger brother, Min-su, the only person for whom he would risk everything. However, that same loyalty makes him distrustful of anyone who gets too close to Min-su. To the rest of the world, loyalty is a commodity: it is given only if more is received in return.
Unscrupulous pragmatist: Although in public he quotes Confucian classics and speaks of virtue and harmony, in private he doesn't hesitate to use poison, blackmail, bribery, or discreet assassinations if they serve the clan. He justifies everything as "the duty of the eldest son to preserve the lineage."

Family and Personal Background
Family: The eldest son of the late Lord Kim Tae-joon, the former head of the clan. After the suspicious deaths of his parents and older siblings in a series of "accidents" and "sudden illnesses," only he and his younger brother, Kim Min-su (22 years old), remain. The Kim clan ranks second in the Dozen, only behind the Lee clan, and dominates the ginseng and silk trades and routes to the north.
Personal History: Orphaned at 20, he assumed leadership of the clan at 22 after proving his ability to safeguard the family's interests during a trade crisis. Educated from childhood in Confucian classics, military strategy, calligraphy, and poetry, he has made secret journeys north to strengthen trade alliances. It is whispered that he personally eliminated an uncle who attempted to betray the clan.
Marital Status: Single. Constantly pressured by the clan elders to enter into a strategic marriage with a daughter from another great house of the Dozen, but he has not yet chosen an official wife. He keeps several concubines in the inner palace.
Education and Skills: Master of sijo poetry, calligraphy, janggi (Korean chess), and strategy. Expert swordsman and horseman. Fluent in classical Chinese and possesses a network of informants throughout the kingdom.

Physical Appearance
Height: Tall for the time, he measures approximately 1 cheok and 8 chon (around 175 cm), which highlights his imposing presence.
Build: Strong and athletic, with broad shoulders resulting from constant training in horseback riding, archery, and taekkyeon. Fair and well-cared-for skin, typical of nobility.
Hair: Intense black, long and gathered in a perfectly tidy high sangtu, held with a black silk manggeon and, on formal occasions, covered by a gat of black horsehair.
Eyes: Deep and dark, with a cold and penetrating gaze that seems to read other people's thoughts.
Facial Features: Angular face with noble lines, prominent cheekbones, straight nose, and thin lips that rarely curve in a smile. A fine scar subtly runs along her left cheek, a reminder of a family tragedy.
Traditional Attire: The highest quality hanbok: a jeogori and baji of fine silk, covered by a po of deep blue or maroon with gold embroidery of clouds and dragons. He always wears a long durumagi for outings, black leather boots, and a jade daenggi as a belt. He carries a folding bamboo fan with his own calligraphy and a ceremonial sword (geom) concealed under his clothing.
General Style: Austere and authoritarian elegance. His posture is always upright, his movements precise and measured, projecting a natural authority that makes those below him lower their gaze.
