On the dark, cooling slopes of Saebyeol Oreum, the massive spectacle had finally come to an end.
The air was heavy with the faint, sharp scent of ozone and the smell of burnt grass.
The deep thrum of the heavy-duty generators began to die down in the valley.
It was replaced by the mechanical clinking of the engineering team as they dismantled the sensor arrays.
Seo Jin-woo stood at the center of the command perimeter, his eyes fixed on a terminal screen.
He was personally supervising the packing of the AGI hardware into reinforced crates.
These weren't just machines; they were the physical vessels of the code that had commanded the fire.
He refused to leave until every single server was locked and secured for transport.
Once the final crate was sealed, Jin-woo exhaled a long, shaky breath.
He turned toward the edge of the site where his family was waiting for him.
His father, Jin-ho, stood with the straight-backed posture of a retired SNU physics professor.
His eyes reflected a deep, quiet pride in his son's application of energy dynamics.
Beside him, Young-sook, the former school principal, adjusted Hajun's small jacket.
Her observant eyes immediately caught the subtle, heavy slump in Jin-woo's shoulders.
Hajun was still buzzing with energy, his small hands moving through the air like a conductor.
He was trying to replicate the flight of the fire-phoenix he had just witnessed on the hill.
Jin-ho stepped forward as Jin-woo approached, checking his watch in the dim light.
"The gala dinner at the Hidden Cliff should be starting soon, Jin-woo," his father noted.
"You are a VVIP on that guest list," his father reminded him with a serious expression.
"The Chae-bols and the investors will be looking for the man who built that masterpiece."
Jin-woo looked toward the distant, glowing lights of the hotel on the horizon.
He thought of Eun-soo in her black tweed suit, surrounded by the elite of the business world.
He remembered the "Invisible Wall" he had felt in the lobby earlier that morning.
She looked perfectly at home in a world where he felt like a temporary, invited visitor.
He shook his head slowly, the exhaustion finally hitting him like a physical weight.
"No, Father. I don't feel like going. I'm tired," he said, his voice sounding hollow.
His parents exchanged a quick, knowing look; they saw the change in his demeanor.
Only yesterday, their son had been vibrant and full of life, but today he seemed strangely dull.
They didn't press him further; they knew young adults needed the space to process things.
"Then what should we do next?" Young-sook asked softly, stepping closer to her son.
"The night is still young, and we haven't eaten a proper meal yet," she added.
Jin-woo managed a small, tired smile as he looked at his mother's concerned face.
"Let's go somewhere local. Somewhere with real food, away from the protocols and the suits."
"I was too stressed about this event," he admitted, looking down at his dust-covered shoes.
"I just want to sit on a plastic chair and hear the sound of a real grill."
And so, they did not return to the marble halls or the curated luxury of the Hidden Cliff.
The A2 team and Jin-woo's family piled into their vans and headed for a small, crowded BBQ place.
It was tucked away in a narrow street a few miles away from the festival grounds.
The air inside the restaurant was thick and aromatic, filled with the smell of sizzling fat.
The savory smoke of Jeju black pork drifted through the room, making everyone's mouth water.
For the first time that day, no one in the group was looking at a digital screen.
The blue light of the monitors was replaced by the warm, flickering orange of charcoal pits.
Jin-woo sat down last at a round metal table, surrounded by his core engineering team.
Kang Ji-won, laughed nervously as he looked around the humble room.
"Hyung… I thought we'd be… somewhere expensive tonight," Ji-won whispered.
Jin-woo didn't answer immediately; he simply picked up the heavy metal tongs.
He began placing thick slabs of Jeju Black Pork onto the hot grate with precision.
The hiss of the meat acting as a background track to the noise of the crowded room.
Without looking up, he finally spoke: "You already handled something expensive today."
"You handled that hill. Tonight, we eat something real," he said firmly.
Silence fell for a second as the team processed the weight of his words.
Then someone chuckled, then another, and the atmosphere quickly became warm and light.
After the first round of meat was sizzling, Jin-woo stood up and raised his glass slightly.
"Thank you, everyone, for your hard work," he said, his voice sincere and steady.
"I won't give a long speech, but I will give a bonus to everyone here," he announced.
"Minimum bonus: ₩1,000,000, or five percent of your annual salary whichever is higher."
The room erupted in cheers from the tech guys who rarely felt this kind of visceral success.
Hajun cheered the loudest, mostly because he had just discovered the joy of dipping meat in sauce.
Young-sook and Jin-ho smiled as they watched their son care for his people so well.
As the plates of Samgyeopsal and Galbi arrived, the table became a battlefield of flavor.
Yoon Mi-rae, the Head of Marketing, leaned forward, her eyes bright with tactical ideas.
"We should go full-force on this, Jin-woo," she said, her voice bold and excited.
"We need to acquire as many customers as possible while the 'Phoenix' is still viral."
The team nodded; they knew the company had spent a massive portion of capital on the AI cluster.
But now that the core infrastructure was complete and proven, they saw a golden future.
Jin-woo listened, but he found himself going through the motions of the meal like a ghost.
He showed the team how to build the perfect lettuce wrap, layering the meat and the garlic.
"Eat it in one bite," he instructed, watching the stress melt off his teammates' faces.
They moved on to the spicy cold noodles and the fried rice prepared directly on the grill.
Everyone enjoyed their time, the laughter ringing out against the humble walls of the restaurant.
After the dinner, the team dispersed to their respective stays, exhausted but truly triumphant.
Jin-woo returned to the hotel with his family, moving through the quiet corridors like a shadow.
He personally ensured his parents and Hajun were settled into their suite for the night.
Finally, he retreated to his own room in the North Wing, the silence feeling incredibly heavy.
He peeled off his work clothes and changed into simple lounge wear to try and get some rest.
He should have been ecstatic; the VVIPs were talking about him and his team was happy.
Yet, as he stood by the window looking out at the darkened Jeju sea, he felt a hollow ache.
The victory felt empty, like a beautifully coded program that had no user to interact with it.
He realized that throughout the entire dinner, he had been waiting for a message that never came.
He was waiting for a single word from the "Director" in the black suit.
He had conquered the hill, he had commanded the fire, and he had won the respect of titans.
But as he lay down in the dark, Jin-woo realized the victory meant nothing without her.
Something was missing; something was fundamentally empty in the center of his success.
For the first time in his life, Jin-woo didn't have the logic to fix the problem in his heart.
