On the top floor of Hanwol International School, behind glass doors and thick silence, lies a special classroom few students ever enter.
It's called "S-Gold Class" — short for Scholar Gold Division.
This is where the school's elite gather: the heirs of business empires, politicians' children, and the truly "untouchable."
At the center of the room sits a calm, sharply dressed boy — Lee Jun-hae — the only son of the man who owns the entire Hanwol education foundation.
He has the face of a chaebol heir — flawless skin, perfectly combed black hair, and a wristwatch that costs more than most people's rent.
But beneath the elegance, Jun-hae is dangerous.
He doesn't speak often.
But when he does, people listen.
Seated to his left and right are his two closest friends:
Min Jae-suk, son of a high-ranking government education official.
Kang Dae-hyun, grandson of a K-pop industry tycoon.
Across from them, three girls sit.
Two of them are scrolling their phones and giggling about some trending SNS post.
But the third girl sits quietly, eyes focused on a thick novel in her hands.
Long black hair, simple silver earrings, and a composed aura.
Her name is Seo Yoon-ji — calm, elegant, and quietly different from the rest.
Then, Dae-hyun breaks the peace.
"Did you hear? There's a new student today."
Jae-suk raises an eyebrow. "The one from overseas?"
Seo Yoon-ji slightly lifts her gaze from her book.
"From America, right?" Dae-hyun adds.
Jun-hae, who hadn't said a word all this time, gently closes his laptop.
"His name's Roby Moreno."
Jae-suk grins. "How do you already know that?"
Jun-hae smirks faintly.
"My father doesn't like surprises. Every new student goes through his desk... and mine."
Seo Yoon-ji speaks softly, neutral in tone.
"Who is he?"
Jun-hae looks out the window, towards the main building below.
"We'll find out soon enough.
Whether he's just another transfer student… or something far more interesting."
The class bell had already rung, but the teacher hadn't arrived yet.
Students were chatting, laughing, passing notes. Typical chaos.
Roby leaned slightly to his right, glancing at the quiet white boy next to him — the same one who barely reacted earlier.
He reached out a hand casually.
"Roby Moreno," he said with a small smile.
"Pretty sure desk buddies are supposed to say hi."
The boy turned his head slowly.
His gray eyes were expressionless, almost empty.
He responded with just one word:
"...Lucas."
Roby waited for a handshake.
Lucas simply looked away and went back to scribbling in his notebook.
Roby pulled back his hand, grinning lazily.
"Not a handshake guy. Cool. I respect that."
He leaned back in his chair, glancing across the room.
His eyes found Nam Do-yoon, slouched at the window seat, one earbud in, hoodie halfway on, scribbling on a page full of chaotic writing.
Even from across the room, Roby could catch that faint cigarette smell still clinging to him.
Roby murmured to himself with a smirk,
"Nam Do-yoon... silent but smells like he's been through a street fight with time."
His eyes shifted again—this time toward the front row.
There she was.
The loudmouth girl from earlier, sitting tall and commanding a small group like she was royalty.
Roby caught murmurs from other students nearby.
"Oh god, Ha Rin's already starting..."
"She really acts like she runs this school."
"Did her dad buy her a personality?"
Ha Rin.
That name—Roby locked it in.
She was flawless by school standards: wavy light brown hair, glossy lips, sparkly nails, and attitude thicker than her foundation.
Every time she said something, people listened—whether they wanted to or not.
Roby eyed her from his seat, smirking, and whispered to Lucas without turning his head.
"That's Ha Rin, right?"
Lucas didn't respond.
Roby chuckled to himself.
"Yep. Got my answer."
He folded his arms, relaxed.
The stage was being set.
The actors were stepping forward.
And like always... Roby was ready to stir the script — in his own unpredictable, chaotic, loudmouth way.
The classroom door swung open quietly.
A woman with short hair, glasses, and a no-nonsense look stepped in, carrying a tablet and a stack of books.
"Good morning, class," she said firmly.
"Good morning, Ms. Yoon," the students replied in unison.
Roby glanced around and mimicked softly,
"...Good morning, Ms. Teacher."
Ms. Yoon opened her attendance app.
"Today, we're continuing with World History. Open your notes to page 6. We're covering the Industrial Revolution."
Roby opened his notebook.
Blank. Not a single word. The pages still smelled fresh from the store.
He peeked at Lucas beside him.
Lucas had his book open—clean, handwritten notes, color-coded highlights, precise margins.
Roby whistled quietly.
"Your notebook looks like it belongs in a museum..."
Lucas gave him a side glance.
"Don't look at mine."
Roby grinned. "Wasn't looking. Just... admiring."
Ms. Yoon scanned the class.
"Alright. Who can explain the main factors behind the Industrial Revolution in England?"
Silence.
Nam Do-yoon, from the back corner, lazily raised his hand.
But before his name was called—
"Me, ma'am!"
All heads turned.
Roby sat up straight, wearing his usual half-smirk.
Ms. Yoon raised an eyebrow. "The new student… Moreno?"
"Yes, ma'am. But just call me Roby. We'll be besties in no time."
A few snickers from the back.
Ms. Yoon gestured. "Go ahead."
Roby stood up slowly, one hand in his pocket, casually pointing to the blank whiteboard.
"The Industrial Revolution was triggered by several factors: natural resources like coal and iron, political stability in England at the time, colonies that served as both markets and resource suppliers, technological innovation like the steam engine and spinning machines… and early capitalism that encouraged industrial investment."
The room went quiet.
Students looked around, muttering.
"Damn, the cocky guy nailed it..."
"Where the heck did he read that?"
Even Ms. Yoon looked down at her tablet.
She gave a small, surprised smile.
"That is one hundred percent correct."
Roby sat back down, whistling softly.
Lucas turned to him.
"You didn't even have notes."
Roby tapped his temple with two fingers.
"Bro, everything's in here.
This isn't empty. It's a weapon vault."
From the front row, Ha Rin shot him a sharp look.
Her lips curled in disdain, but... her eyes flickered with curiosity.
