god of baduk
By 류벼리
A room in a dilapidated high school on the outskirts of Seoul.
Twenty-three-year-old Junyeol stared at the ceiling at night and tried to sleep: a ten-hour-a-day job, the smell of stale ramen noodles, and a forgotten talent. In elementary school, he had won a broadcast with an IQ of 173, but now he was stocking chocolate bars at a convenience store. His parents' bankruptcy, divorce, and welfare blind spots made him “just a kid,” not a “genius.”
That day, he was taking out the trash, exhausted. He was taking out the trash one day when he saw an old man on a park bench with a checkerboard.
“Do you want to play?”
Suddenly, Junyeol's brain went strangely quiet. The moment he grabbed the stone, thousands of possible outcomes raced through his mind. It was more sophisticated than math, deeper than organs. A game over in a matter of minutes. The old man said without a smile.
“You have a talent.”
From that day forward, he played Go every night. He bought second-hand go books, read them, and registered on an online go site under the name “Black Heaven”. At night, he threw stones at the world with his mouse from his study room. The nameless user was racking up wins at a frightening rate.
“Isn't this guy a pro?”
“Isn't he an AI?”
Speculation and rumors abounded, and eventually, an invitation to the International Go Championship arrived. Anonymity allowed. No identity. But proven to be skilled.
His final opponent was Ren Arakawa, a young Japanese prodigy. Ranked number one in the world.
A 19x19 universe of black and white stones. In it, Junyeol forgot the damp ceiling of the high school and the pain of his part-time job. A number no one had ever imagined, a shape no one had ever read.
The narrator lowered his voice.
“That's... not a number humanly conceivable.”
Forty-five minutes later, Ren set the stone down.
“I admit defeat.”
Even at that moment, Jun's name was not revealed.
Reporters asked:
“Who is Black Heaven?”
But he was still sitting in his study, quietly reviewing his kibo.
The world didn't know him, but no one ignored him on the board.
And today, he thought of another move.
“Now, my life begins.”
🧠 1. Main Character - 'Lee Joon-Yeol' (Nickname: Black Cheon)
Item
Setting
Age
23 years old
Gender
Male
Height / Body type
177cm / skinny, slightly hunched shoulders
Appearance
Sharp forehead, dark circles under eyes, dark eyebrows and clear eyes. Few words, few facial expressions, but eyes say it all.
Hairstyle
Dark hair, naturally disheveled with a stop-start look. Forehead is barely visible.
Clothing style
Old hooded zip-ups, convenience store uniforms, gray jumpers from thrift stores. Black long coat and hat for Go tournaments (to remain anonymous)
Personality
Genius but modest. A man of few words, but sharp in observation and concentration. Socially cynical, but has a warm sense of justice inside. A strong mind, not easily swayed by anything.
Habits
When reading numbers, he moves his fingers in a hollow motion. Bites his lips absentmindedly.
Characteristics
Genius with an IQ of 173. Quick reasoning and intuition. Exceptional spatial awareness and ability to analyze patterns.
📌 Tip: Jun-yeol is like a “black lotus flower growing where the light doesn't reach” character.
Portraying him as a quiet genius who blooms out of a dark reality will make the emotional lines of the drama come alive.
🧓 2. Old man in the park - 'Jung Young-gu' (as a go master)
Item
Setting

🏚️ 1. Gosiwon “Dawn Jar”
Item
Description
Location
On the outskirts of Seoul, in an old redevelopment area
Appearance
Hallways narrow, drab wallpaper, fluorescent lights flicker frequently. Wind leaks in through doorways, no soundproofing at all.
Interior
Room is about 1.5 square meters. A mattress as a bed, a small folding desk, and a single wall fan. Low ceilings and dingy wallpaper. Few windows.
Functional meaning
Symbolizes ‘the fall of genius’ and ‘the pain of reality’. The isolated space is the starting point for Jun-yeol's rediscovery of Go and his talent.
Emotional Tone
Dark, subdued atmosphere, full of silence instead of noise.
📌 Tip: Use this barely lit space as a **‘mirror of psychological darkness’** to create a more dramatic contrast with the light on the checkerboard.
🌳 2. Neighborhood Park - ‘Teal Park’
Item
Description
Location
Small low-lying park, 5 minutes walk from the high school
Appearance
A few benches, one dead tree, a grassy area and an old playground. Only one streetlight flickers on at night.
Feature
The place where an elderly man, Jung Young-gu, plays Go every day. The place where Jun-yeol first fell in love with Go.
Functional meaning
A place where ‘fateful encounters’ take place. This quiet, secluded space acts as a small time and space portal that shifts the story.
Emotional tone
Analog, old, peaceful, and nostalgic.
📌 Tip: The park can be described like a **‘secret dojo’** of a master and disciple. Emphasize the feeling of disconnection from the outside world!
🖥️ 3. Online Go Community - ‘Go Constellation’
Items
Description
Platform Personality
Global Go site. No real names required. Rankings are based on skill and real-time analysis AI.
Visual Features
Ranking map like a constellation on a black background. Each user uses the name of a star. Junyeol plays as ‘Black Heaven’.
Functional meaning
A space where talent explodes in anonymity. The first ‘real competition’ with the world. The stage where Junyeol's real growth begins.
Emotional Tone
A futuristic, colorless, emotionless world of information, but the heat of a fierce battle flows through it.
