The afternoon sun hung low over Shinseong High, casting long shadows across the courtyard as students poured out of the main building in lively groups.
Some headed straight for the gates, eager to get home after another long day of classes. Others lingered beneath the trees, stretching conversations that had already lasted through lunch. Members of various clubs drifted toward their activity buildings, uniforms gradually disappearing beneath jackets and backpacks as the school settled into its familiar after-school rhythm.
Among the crowd, Jae-Hyun walked beside Jae-Suk and Tae-Ho.
"So," Tae-Ho began, rocking back on his heels as he walked, "I'd just like to point out that today's mission was a complete success."
Jae-Suk glanced at him. "What mission?"
A grin spread across Tae-Ho's face. "The Ri-Na mission."
"Thanks to a certain someone..." He nudged Jae-Hyun with his elbow. "...I've finally made progress."
Jae-Hyun didn't even look at him. "You've confused 'I'll think about it' with 'yes.'"
Jae-Suk's eyes drifted toward Jae-Hyun. "You actually asked her?"
"I didn't have much of a choice," Jae-Hyun replied. "He wouldn't let it go."
Tae-Ho laughed without the slightest bit of guilt. "I had to make the most of the opportunity."
"I heard you dragged him across the classroom," Jae-Suk said, shaking his head.
"I guided him."
"They said you were holding his wrist."
"So he wouldn't escape."
Jae-Hyun looked at him. "I wasn't planning to run."
"You say that now." Tae-Ho shrugged, entirely pleased with himself. "Either way, it worked."
Jae-Suk smiled faintly. "But she didn't agree."
"She said she'd think about it."
There wasn't even a trace of disappointment on Tae-Ho's face. He sounded genuinely satisfied. "That's the first time she hasn't turned me down immediately."
Jae-Suk gave a small nod. "I'll admit... that's progress."
"It is, isn't it?" Tae-Ho said, looking far too proud of himself. "Give me another month and she'll be teaching me everything she knows."
Jae-Hyun glanced sideways at him. "You've already planned the lessons."
"I've planned the celebration too."
Jae-Suk couldn't help laughing. "I admire your confidence."
The three shared an easy laugh as they continued down the gently sloping path toward the front gate.
After a while, Tae-Ho looked between the other two. "So... where are we going today?"
Jae-Suk thought for a moment. "We were at your house last weekend."
"Exactly," Tae-Ho said. "Which means this time we should go to yours."
Jae-Suk shook his head. "We were there the week before."
"Were we?"
"You ate half my mother's fried chicken."
Tae-Ho frowned, trying to remember. "...I did?" His eyes wandered toward Jae-Hyun. "Then let's go to your place."
"We still haven't seen the new house," Jae-Suk added. "You've been there for weeks."
Jae-Hyun slipped his hands into his pockets as they walked. "You'll see it eventually."
"That's not a yes," Tae-Ho pointed out.
Before either of them could say anything else, his expression suddenly brightened.
"Actually..." He snapped his fingers. "I've got a better idea."
Jae-Suk looked at him with quiet suspicion. "Should I be worried?"
"We should go to your mom's restaurant instead."
Jae-Hyun looked over. "My mother's restaurant?"
"Think about it," Tae-Ho said, already warming to the idea. "We haven't been there since it reopened. I bet the new place is way bigger."
"We'd spend half the time helping out," Jae-Hyun replied.
"So?" Tae-Ho smiled. "We'll help when it's busy. And when it's not? We eat."
Jae-Suk let out a quiet laugh. "There it is."
"What?"
"The real reason."
Tae-Ho looked genuinely confused. "I wanted to support Auntie."
"You wanted to support her menu."
"I can do both."
Jae-Suk smiled, unconvinced. "I've never met anyone who could turn every plan into food."
Before Tae-Ho could answer, hurried footsteps echoed from somewhere behind them.
"Jae-Hyun!"
All three turned at the same time. Raon jogged across the courtyard, weaving effortlessly through the students ahead of him. He caught up a few seconds later without slowing down, slipping neatly into the space between Jae-Hyun and Tae-Ho.
Before either of them could react, he draped an arm around each of their shoulders.
"So," he asked, slightly out of breath but smiling all the same, "where are we hanging out today?"
Tae-Ho looked at the arm resting across his shoulders before turning to Raon. "...Since when did this become your after-school routine?"
Raon blinked. "Since we're friends."
Jae-Suk folded his arms. "I don't remember inviting you."
"You didn't have to." Raon looked between the three of them as though the answer was obvious.
"We eat lunch together." He smiled. "Hanging out afterwards just seemed like the next step."
Tae-Ho scratched the side of his head. "...That sounds reasonable."
"Because it is."
Jae-Suk sighed through a smile. "You've invited yourself into the group."
Jae-Suk and Tae-Ho exchanged a helpless glance before, almost at the same time, looking toward Jae-Hyun.
Jae-Hyun noticed the synchronized movement immediately. "...Why are you both looking at me?"
"You've known him longer," Tae-Ho said.
"Fix this," Jae-Suk added.
Raon frowned. "Why are you talking like I'm causing trouble?"
"You appeared out of nowhere and started making plans with us."
Before Jae-Hyun could answer, his phone vibrated inside his pocket. The sound was quiet, but it was enough to pull his attention away. He slipped the phone out and glanced at the screen.
Chairman. The AI has rejected a ₩3 trillion investment from the Seo Group. It says there's a critical systemic liability hidden in their portfolio. I've reviewed the data three times and I still can't see it. Could you come to Equinox?
The relaxed look in his eyes faded almost imperceptibly.
He read the message once more before locking the screen. "I won't be able to come today."
The others looked at him.
"Something's come up."
Tae-Ho's smile faded. "Work?"
Jae-Hyun nodded once.
Jae-Suk didn't ask another question. "Alright."
Tae-Ho let out a small sigh before glancing toward Raon. "...Then what about him?"
Raon pointed at himself. "Me?"
"Yes, you."
"You just declared yourself part of the group." Jae-Suk added.
"So now what do we do with you?"
Raon thought about it for a second before looking at Jae-Hyun. "...That's a good question. They've got a point."
Jae-Hyun adjusted the strap of his bag before looking at the three of them. "You'll figure something out."
Tae-Ho opened his mouth to object.
"You were already making plans." He gave a small nod toward Raon. "Take him with you."
Before anyone could protest further, Jae-Hyun turned and headed toward the road outside the school gates.
The crowd gradually swallowed him until he disappeared beyond the front entrance.
For a few seconds, the remaining three simply watched him leave.
Then Raon stepped neatly between Tae-Ho and Jae-Suk.
He draped an arm around each of their shoulders with effortless familiarity.
"So..." he asked with an easy grin, "...whose house are we going to?"
Tae-Ho slowly looked at Jae-Suk. Jae-Suk slowly me his eyes. Neither of them spoke. Then, almost in unison, they let out the same long-suffering sigh.
Raon looked from one to the other. "...I'll take that as nobody's decided yet."

By the time Jae-Hyun arrived at Equinox Funds, dusk had begun settling over Seoul.
The glass façade reflected the fading orange sky while the company logo glowed softly above the entrance, its silver lettering catching the last rays of sunlight.
The glass doors of Equinox Funds slid open as Jae-Hyun stepped inside. The lobby was calm despite the steady rhythm of ringing phones and quiet conversations drifting from the trading floor beyond.
Employees moved with practiced efficiency, carrying documents between departments while market data scrolled endlessly across the monitors mounted along the walls.
The receptionist looked up from her desk. "Good afternoon."
Jae-Hyun gave a polite nod as he signed the visitor log beside the desk. "Good afternoon."
She handed him a temporary access card with an apologetic smile. "Mr. Nam is expecting you. The executive elevator is through there."
"Thank you."
He clipped the card to his blazer and walked toward the restricted corridor. A security gate flashed green. The elevator doors opened almost immediately.
By the time they closed again, the receptionist had already returned to answering another phone call.
The executive floor was almost silent. The elevator doors parted revealing Mr. Nam who was already waiting outside.
The older man's posture remained composed, but the tension in his expression hadn't eased since sending that message. "Chairman."
Jae-Hyun stepped out. "Show me."
Mr. Nam turned immediately. "This way, sir."
The two walked side by side through the quiet executive corridor. A few employees glanced up as they passed before bowing respectfully to Mr. Nam. A few moments later, the office door closed behind them.
Mr. Nam walked straight toward the interactive conference table occupying the center of the room. The glass surface illuminated beneath his fingertips.
"I've reviewed it repeatedly," he began, pulling up the evaluation report. "The client's documentation is clean. Asset verification is complete. Capital origin has been confirmed. Tax compliance, regulatory filings, anti-money laundering screening... everything passed."
The report expanded across the tabletop. Streams of interconnected ownership structures slowly rotated above the glass.
"I even reviewed the underlying datasets myself." Mr. Nam looked toward Jae-Hyun. "I thought perhaps the AI had made an error."
"It didn't."
The answer came quietly.
Without another word, Jae-Hyun stepped closer to the table. His fingertips brushed lightly across the projected interface.
The ownership map expanded. Hundreds of companies spread outward like an intricate web suspended above the glass.
He enlarged one section. Studied it. Then another. The network rotated slowly beneath his hand. Company names drifted past one another. Holding companies, subsidiaries, investment vehicles, private family offices, Joint ventures.
Mr. Nam remained silent. He'd seen Jae-Hyun analyze complex financial structures before. Usually... It didn't take this long.
Jae-Hyun zoomed farther in. A cluster of subsidiaries separated from the larger network. He selected several. Their financial reports appeared one after another.
Revenue remained healthy. Cash flow was stable. Debt ratios sat comfortably within industry standards, while collateral and loan guarantees showed nothing unusual.
He closed them again. He opened a different section, another group of companies. Again... Healthy.
The office grew steadily quieter. The faint hum of the AI server became strangely noticeable.
Mr. Nam folded his hands behind his back. He hadn't intended to interrupt, yet every passing second tightened the knot in his chest. If even the Chairman needed this much time, then perhaps the AI really had uncovered something no one else could see.
Jae-Hyun finally stopped moving. The ownership network froze above the table. His eyes rested on the glowing web for several silent moments.
Then—
"Reject it."
Mr. Nam blinked. "...Chairman?"
"The proposal is too dangerous."
His brows drew together. "I don't understand." He stepped closer to the display, gesturing toward the report. "Everything checks out."
Jae-Hyun looked at him. "Individually."
The single word lingered between them. Mr. Nam frowned. "The AI identifies a critical interconnected liability. But I can't find it."
Jae-Hyun rested one hand lightly against the edge of the table. "How many companies does the Seo family control directly?"
Mr. Nam answered almost immediately. "Thirty-two."
"And indirectly?"
Mr. Nam paused. "...Approximately one hundred and eighty, depending on how minority holdings are classified."
Jae-Hyun gave a small nod. "How many of those companies guarantee debt issued by another company within the same group?"
Mr. Nam looked back toward the ownership map. His eyes narrowed slightly. "...Quite a few."
"How many?"
He hesitated. "I haven't counted."
Jae-Hyun didn't comment. Instead, he selected one of the subsidiaries. A series of financial records unfolded above the table.
"This company." He tapped another. "What secures its largest loan?"
Mr. Nam scanned the report. "A corporate guarantee."
"From whom?"
He followed the document downward. "...Another Seo subsidiary."
Jae-Hyun selected that company next. "And theirs?"
Mr. Nam continued reading. His expression shifted almost imperceptibly. "...Also guaranteed."
"By?"
"...Another company inside the group."
Jae-Hyun nodded once. "And that company?"
Mr. Nam opened its filings.
Silence.
His eyes moved more slowly now. "...Guaranteed..."
He stopped speaking.
Jae-Hyun waited.
Mr. Nam looked back toward the ownership network. His gaze traveled from company to company. One guarantee. Another. Then another.
His breathing slowed. "...They're guaranteeing each other."
Jae-Hyun gave a small nod. "Every company looks healthy on its own."
His fingers swept across the ownership web, collapsing dozens of subsidiaries into a single interconnected structure. "But businesses don't fail in isolation."
The network tightened as lines of debt, guarantees and collateral converged into a dense web. "When one falls..."
A single company on the display dimmed. Like falling dominoes, the surrounding companies followed.
Within seconds, nearly the entire structure had turned red.
Mr. Nam watched the simulation unfold in silence. "...A chain reaction."
Jae-Hyun's gaze remained on the display as he zoomed farther out. Clusters disappeared one after another until only the Seo family's network remained.
He studied it in silence. His fingers made a small adjustment and another layer vanished.
For a brief moment, a different cluster appeared near the edge of the display.
Shinseong Foundation.
Hanseong Education Trust.
Cheongrim Cultural Foundation.
The filter continued processing. The cluster disappeared with the rest. Jae-Hyun's attention never left the Seo network.
"Here." He enlarged a chain of guarantees. "This is where it begins."
The realization was still unfolding. Mr. Nam reached out instinctively, rotating the ownership web himself.
More connections appeared. Mr. Nam looked back at the AI's warning. Estimated probability of cascading liability exposure: 97.84%.
For the first time since the report appeared the number no longer felt exaggerated.
He looked toward Jae-Hyun. "...This isn't one company's problem. Even a chain reaction is an understatement."
Jae-Hyun's eyes remained on the glowing web suspended above the table.
"Exactly." His voice was calm. "It's an ecosystem."
Mr. Nam remained silent for several moments, his eyes lingering on the web of interconnected companies still suspended above the table.
Finally, he let out a slow breath. "...I'll reject it."
Jae-Hyun gave a small nod.
"They've requested a meeting," Mr. Nam continued. "Their representative insisted on speaking in person."
"When?"
"Tomorrow morning."
"Confirm it."
Jae-Hyun closed the projection with a sweep of his hand. The intricate ownership web dissolved, leaving only the faint reflection of the office lights on the glass tabletop.
As he picked up his school bag, Mr. Nam spoke again.
"...Should I simply decline?"
Jae-Hyun paused.
"No." He turned slightly. "Tell them why."
Mr. Nam frowned. "The guarantees?"
"Not the details." Jae-Hyun adjusted the strap over his shoulder. "Just enough for them to understand the risk."
Mr. Nam inclined his head. "I understand."
Jae-Hyun took a few steps toward the door before stopping once more. "And one more thing."
Mr. Nam waited.
"We're rejecting the proposal, but I don't want you to send them away empty-handed. Advise them to review every cross-guarantee and every intercompany liability in their group."
He looked back. "If they act quickly, they'll still have time to contain the damage."
A faint smile appeared on Mr. Nam's face. "I'll make sure they understand."
Jae-Hyun gave a single nod before leaving the office.
The elevator descended in silence. By the time the doors opened onto the lobby, he had already taken his phone from his pocket.
He scrolled through his contacts for a moment before pressing Mr. Oh.
The call connected almost immediately. "Good evening, Chairman."
"I need you to come to my house."
There wasn't even a hint of surprise in Mr. Oh's voice. "What time?"
"As soon as you're finished at NovaSec." Jae-Hyun stepped out through the lobby and into the cool evening air. "I have something I need you to do."
"Understood. I'll be there."
Jae-Hyun ended the call and slipped the phone back into his pocket as he continued toward the waiting car.
