Beneath the billonaire's gaze

Lee Hana stood across the street from the towering glass structure, her fingers tightening around the stack of files pressed against her chest.

JH Group Headquarters.

The building pierced the sky like a silent declaration of dominance-steel, glass, and power wrapped into one intimidating monument. Employees streamed in and out with practiced confidence, dressed in sharp suits and polished shoes, as if they belonged to this world.

Hana did not.

She swallowed hard, forcing herself to breathe.

It's just one day, she reminded herself. Just one.

If her cousin Minji hadn't called in sick at the last minute, Hana would be nowhere near this place. Minji had begged her over the phone, voice weak and apologetic, insisting it was only a temporary secretary position-easy work, no pressure. Just answer calls, organize documents, and stay invisible.

But now, standing before the headquarters of one of the most powerful conglomerates in the country, Hana felt painfully visible.

She adjusted her modest blouse, smoothed her skirt, and crossed the street.

The lobby was vast and gleaming, marble floors reflecting the light from the chandelier above. The air smelled faintly of expensive cologne and freshly brewed coffee. Hana's heels clicked nervously as she approached the reception desk.

The receptionist barely glanced at her, scanning her name before sliding a visitor's badge across the counter.

"Top floor," she said curtly.

Hana nodded and headed toward the elevator, her heart pounding harder with each step.

Inside the elevator, she stared at her reflection in the mirrored walls. Her face looked pale, eyes wide with nerves. She didn't belong here-she knew that. But today, she had no choice.

The elevator chimed softly as it reached the top floor.

Taking a deep breath, Hana stepped out and followed the signs toward the CEO's office. With every step, Minji's hurried instructions echoed in her head.

Don't mess up. Don't bother the boss. And whatever you do-do not draw attention.

Easy enough.

The office door was wide open.

Inside, Kang Jae-Hyun sat behind a massive mahogany desk, eyes fixed on the computer screen in front of him. Even seated, his presence dominated the room. He wore a perfectly tailored black suit, his posture rigid, composed, and unmistakably authoritative.

Hana hesitated at the threshold.

This was Kang Jae-Hyun-the billionaire CEO of JH Group. The man tabloids described as ruthless, cold, and untouchable. The man rumored to have built his empire with merciless precision.

She cleared her throat softly.

"Good morning, Mr. Kang," she said, her voice barely above a whisper. "I'm... I'm Minji's cousin. I'll be filling in for her today."

He didn't look up.

"I don't have time for distractions," he said flatly.

The words struck her like ice.

"Yes, sir," Hana replied quickly.

She stepped forward, balancing a tray that held a cup of freshly brewed coffee and a stack of documents. Her palms were slightly damp, her grip unsteady. She placed the files carefully on the edge of his desk and turned to leave, eager to disappear into the background.

That was when disaster struck.

Her heel caught on the edge of the carpet.

Time slowed.

The tray tilted. The coffee cup slipped from her fingers, spinning helplessly through the air. Hana's breath caught in her throat as she reached out instinctively, but it was too late.

The cup tipped.

Boiling black coffee splashed forward.

Straight onto Kang Jae-Hyun's chest.

The liquid spread across his crisp white shirt, staining it instantly.

Silence.

The room seemed to freeze.

Hana stared in horror as the dark stain bloomed across his chest, her mind blanking completely.

"I-!" Her voice cracked. "I'm so sorry! I didn't mean to-please don't fire me! I'm not even supposed to be here, technically-"

Kang Jae-Hyun slowly rose from his chair.

He picked up a handkerchief from his desk and dabbed calmly at his shirt, his movements controlled, almost unnervingly so. His dark eyes finally lifted to meet hers.

Cold. Sharp. Unreadable.

"You're not Minji," he said.

Hana nodded frantically. "No, sir. I'm her cousin. Well-technically we're not related by blood, but she's like a sister to me and she's sick and I swear this won't happen again-"

"Enough."

One word.

Her mouth snapped shut instantly.

He studied her for a long moment, as if weighing something unseen. Then, unexpectedly, the corner of his lips twitched-barely noticeable, but unmistakable.

"What's your name?" he asked.

"Lee Hana," she replied softly.

His gaze lingered. "You're bold."

Her brows furrowed. "I-what?"

"Most people would already be crying."

She swallowed. "Only because I'm scared."

For a brief second, something flickered in his eyes.

He let out a short, quiet chuckle-so quick she almost wondered if she imagined it.

"You'll do," he said.

Hana blinked. "...Do?"

"For now," he replied, turning back to his desk. "Sit down. We have work."

Still stunned, Hana took a seat at the side desk, her heart racing. The rest of the day passed in a blur of paperwork, phone calls, and document sorting. Despite her nerves, she worked carefully, determined not to make another mistake.

Hours later, after organizing the final batch of documents, Hana stood and approached his desk again.

"These are the files you asked me to sort," she said, placing them neatly in front of him.

Kang Jae-Hyun skimmed through them, his eyes sharp, missing nothing.

"Good," he said.

Relief washed over her.

Then he glanced at the clock.

"Go home. It's late."

Hana hesitated. "Yes, sir."

She turned to leave, then paused when his voice stopped her.

"Come back in three days."

She turned back, surprised. "Why, sir?"

His gaze lifted, locking onto hers with quiet authority.

"Follow my instructions," he said coolly. "Without question."

"Yes, sir," Hana replied.

She left the office with her heart pounding, unaware that a single spilled cup of coffee had just changed the course of her life forever.

JH Group Headquarters, Seoul - 9:15 a.m.

Lee Hana stood in front of the glass elevator, her reflection staring back at her like a question she wasn't sure she could answer.

The JH Group tower rose above her-cold, sleek, and intimidating. Every inch of the building screamed ambition and control. This wasn't just a workplace. It was a battlefield.

"Just pretend you've done this a thousand times," she whispered, adjusting the strap of her tote bag.

She stepped inside the elevator.

She was ten minutes late.

The doors slid open on the thirty-seventh floor-Executive Management.

The air felt heavier here. Quieter. Like even sound knew better than to linger.

"Miss Lee Hana?"

A woman in a fitted navy suit approached her, a headset clipped neatly to her ear.

"Yes," Hana replied quickly. "I'm here to start work. Temporary secretary for-"

"CEO Kang Jae-Hyun," the woman finished crisply. "Follow me."

Hana's stomach dropped.

Straight to the lion's den.

She followed silently, heels echoing against the polished floor as they passed frosted glass walls and minimalist art pieces that probably cost more than her yearly rent.

The assistant knocked once and opened the door.

"Sir, your temporary secretary has arrived."

"Let her in."

Hana stepped forward.

Kang Jae-Hyun stood near the window, his back to her, hands tucked into his pockets. The city stretched endlessly beneath him.

"I remember you," he said without turning.

Her heart skipped. "S-sir?"

"You spilled Americano on my shirt three days ago."

She winced. "I'm really sorry. Again."

He turned slowly.

Up close, he was even more intimidating-sharp jawline, dark eyes devoid of warmth, composure carved into every movement.

"You're late," he said calmly.

"Yes, sir. It won't happen again."

Silence stretched.

Then-"I'll give you one week. Prove your worth."

Relief flooded her. "Thank you, sir."

"There's an NDA on your desk," he continued. "Sign it. Everything that happens on this floor stays here."

"Yes, sir."

"And," his gaze sharpened, "there will be no personal relationships with anyone here. Especially not me."

Her cheeks burned. "Understood."

He dismissed her with a nod.

Hana moved to the desk outside his office and opened the orientation folder-company rules, emergency procedures, legal clauses dense enough to scare off lawsuits.

She signed.

Her phone buzzed.

Kang Jae-Hyun:

Meeting with Yoon & Kim Legal moved to 2 p.m. Update schedule.

She glanced up. He hadn't moved. Hadn't looked at her.

So he texts instead of speaking...

She got to work.

12:30 p.m. - Lunch Hour

Most of the floor emptied. Hana barely noticed.

"Don't forget to eat."

She looked up, startled.

"You've been working nonstop," Jae-Hyun said, already grabbing his coat. "Don't faint before five."

He left.

She stared after him, then shook her head, smiling slightly.

She pulled out her modest lunch-simple, homemade.

"New girl?"

She turned to see a man in a gray suit, warm eyes and an easy smile.

"Seo-Jun. Marketing Director."

"Lee Hana."

He chuckled. "You're brave. Not many last a week with the Ice King."

"Ice King?"

"You'll see."

They laughed quietly.

Unseen behind closed blinds, Kang Jae-Hyun watched.

Then he closed them.

3:00 p.m.

"Bring the Kim Legal file. Now."

She complied.

"Don't talk to Seo-Jun too much," Jae-Hyun said without looking up.

"Is that a rule?"

A faint smirk. "Should I add it?"

Her heart skipped.

Boardroom - 4:55 p.m.

When a senior executive tried to blame Hana, Jae-Hyun shut it down instantly.

"That mistake wasn't hers."

The room fell silent.

Hana didn't breathe.

Afterward, she whispered, "Thank you."

"I don't tolerate incompetence," he replied. "Especially not misplaced blame."

6:30 p.m.

"Hana."

Her name. From his lips.

"Tomorrow. 9 a.m. Sharp."

They rode the elevator down in silence.

At the lobby, he said quietly, "Eat something real tonight."

She watched him leave.

"...Why does that sound like a threat and concern at the same time?"

Lee Hana was still trying to process what had just happened.

He remembered the coffee incident.

And he didn't fire me.

Her legs moved before her brain could catch up.

By the time she realized it, she was already sitting stiffly in the chair opposite Kang Jae-Hyun's massive glass desk, her hands folded tightly in her lap. Her heart pounded so loudly she was sure he could hear it.

Was this a joke?

A test?

Or was she about to be escorted out by security?

"I'm not sure what I'm supposed to do," Hana admitted nervously, her voice barely steady.

"Neither am I," Jae-Hyun replied calmly as he stood. He shrugged out of his blazer, wincing slightly as he glanced at the dark coffee stain. "But you might as well make yourself useful."

Before she could respond, he walked to a cabinet near the wall and pulled out a neatly folded shirt.

Then-without hesitation-he began unbuttoning the ruined one.

Hana's eyes widened.

"Sir! Y-you're changing!"

She turned her head so fast she nearly gave herself whiplash.

"Relax," he said dryly. "I've had assistants faint in this office. You're not the first person to see a man without a shirt."

"That doesn't make it better!" she snapped. "A warning would help!"

A low chuckle escaped him.

Hana froze.

That was the second time.

Rumor had it the Ice King never laughed. Never smiled. Never softened.

Yet here he was-amused.

Once he'd changed, Jae-Hyun returned to his seat and studied her openly, his gaze sharp but curious.

"You said you're not the regular secretary," he said.

"No, sir. Just filling in. My friend is sick."

"And," he added coolly, "you're clearly desperate for money."

Her face flushed instantly. "Is it that obvious?"

He didn't answer.

Instead, he reached into a drawer and slid a slim folder across the desk toward her.

Hana stared at it.

"What's this?"

"A contract."

Her brows knitted together. "For... what?"

Jae-Hyun leaned forward, resting his elbows against the desk. His expression was calm, calculated-like a man negotiating a merger, not about to drop a bombshell.

"I need someone to pretend to be my fiancée for one month."

The world stopped.

"...I'm sorry," Hana said slowly. "What?"

"You heard me," he replied evenly. "One month. You attend events, smile for cameras, and look at me like you're madly in love."

She blinked.

Hard.

"You'll live with me," he continued. "Wear designer clothes. Say as little as possible to the media."

Her mouth fell open. "Why?"

"My grandfather," Jae-Hyun said simply. "He's threatening to remove me as heir unless I 'settle down.' He'll be returning to Korea next month. I need a convincing relationship in place before then."

Hana stared at him like he'd completely lost his mind.

"And you picked me?" she asked weakly. "The girl who spilled coffee on you?"

"You're not intimidated by me," he said. "That's rare."

She swallowed.

"And," he added bluntly, "you need the money."

Silence fell between them.

"I-" Hana hesitated. "How much?"

"Ten million won."

Her breath hitched.

"Ten... million?"

"That's just the advance," he said. "There's a bonus if you play your part well. Room and board included. Consider it professional acting."

Her heart raced.

This was insane.

Completely insane.

Yet her gaze drifted back to the folder.

Her mother's hospital bills.

Her brother's school fees.

The landlord's warnings.

The nights she went to bed pretending hunger was normal.

She clenched her fists.

"...Can I read the contract first?" she asked quietly.

Jae-Hyun leaned back, watching her with unreadable eyes.

"Of course," he said. "This is a business deal. I don't force partners."

She slowly reached for the folder.

And with that single motion, Lee Hana stepped into a world she was never meant to touch.
