Rain poured heavily over Seoul, turning the glowing city into a blur of neon lights and reflections. Cars moved slowly through the streets, their headlights cutting through the mist like blades. People rushed under umbrellas, trying to escape the cold night.

But one building stood brighter than the rest.

A tall, black tower in Gangnam.

Everyone in the business world knew it.

Pravy Group Headquarters.

And at the top floor, one office light was still on.

Inside, Kang Min-Jae sat quietly behind his desk.

He flipped through a thick stack of files, his expression calm and unreadable. His sharp eyes scanned every page carefully. He didn’t rush. He never rushed.

At just twenty-seven years old, Kang Min-Jae had built Pravy Group into one of the most powerful private security companies in South Korea. Politicians trusted him. Celebrities hired him. Even large corporations relied on him.

But no one truly knew him.

Some said he was cold.

Some said he was ruthless.

Some said he never smiled.

But everyone agreed on one thing.

Kang Min-Jae was dangerous.

A knock echoed softly on the office door.

"Come in," he said calmly.

The door opened, and Park Ji-Hoon walked inside. He was Min-Jae’s assistant and one of the few people who could speak freely around him.

"Boss, the investors are waiting."

Min-Jae checked his watch.

"Two minutes."

Ji-Hoon nodded, but he didn’t leave.

Min-Jae looked up.

"You have something else to say."

Ji-Hoon gave a small smile.

"You always notice."

"What is it?"

"There’s a new recruit downstairs."

Min-Jae leaned back slightly.

"And?"

"She passed every test."

"That's normal."

"In record time."

Min-Jae raised an eyebrow.

"How fast?"

Ji-Hoon hesitated.

"One hour."

Silence filled the room.

That was impossible.

Even elite recruits took at least half a day.

Min-Jae tapped his fingers lightly on the desk.

"Bring her after the meeting."

"Yes, boss."

Ji-Hoon left.

Min-Jae closed the file slowly.

For the first time that night, something caught his interest.

Downstairs, Han Seo-Yeon sat quietly in the waiting area.

She looked calm, but her eyes moved constantly.

Camera in the corner.

Two guards near the elevator.

Emergency exit behind her.

She noticed everything.

Her black jacket was slightly wet from the rain. Her hair was tied back neatly, and her expression was calm but serious.

She wasn’t nervous.

She was ready.

A staff member approached her.

"The boss will see you now."

Seo-Yeon stood immediately.

"Thank you."

She stepped into the elevator. As the doors closed, her reflection stared back at her.

She took a slow breath.

Top floor.

The elevator opened.

The hallway was quiet and elegant. She walked slowly toward the large office door.

Knock.

"Come in."

Seo-Yeon stepped inside.

Kang Min-Jae looked up.

For a moment, neither of them spoke.

Seo-Yeon bowed politely.

"Hello."

Min-Jae studied her.

Han Seo-Yeon. Age twenty-two. No security background. Former university athlete. Perfect test results.

Strange.

"Sit."

She sat calmly.

"Why do you want to join Pravy Group?"

Seo-Yeon answered immediately.

"I need the job."

Min-Jae tilted his head.

"That’s not enough."

She met his gaze.

"I want to become stronger."

Her voice was steady.

Min-Jae watched her carefully.

There was something in her eyes.

Determination.

And something else.

Something hidden.

"Training starts tomorrow."

Seo-Yeon blinked.

"You’re hiring me?"

"Yes."

She bowed slightly.

"Thank you, boss."

Min-Jae nodded.

"One more thing."

She looked up.

"In Pravy Group, we don’t hesitate."

"I understand."

"You’re dismissed."

Seo-Yeon stood and left quietly.

Min-Jae watched the door close.

Interesting.

Very interesting.

The next morning, Seo-Yeon arrived early.

The training room was already filled with recruits. Some stretched. Others talked quietly.

When Seo-Yeon walked in, several people looked at her.

"That's her."

"The new recruit."

"The one who passed in one hour?"

She ignored them.

Ji-Hoon walked in.

"Training begins now."

The exercises started immediately.

Running.

Combat drills.

Reaction tests.

Strategy training.

Many recruits struggled quickly.

But Seo-Yeon moved smoothly.

She ran fast.

She dodged attacks.

She reacted quickly.

Min-Jae watched everything from the observation room above.

Ji-Hoon crossed his arms.

"She’s impressive."

Min-Jae nodded slightly.

"Too impressive."

"You think she’s hiding something?"

"Yes."

Min-Jae’s eyes followed Seo-Yeon carefully.

No wasted movement.

No hesitation.

She wasn’t just talented.

She was trained.

After hours of training, only five recruits remained.

Seo-Yeon stood among them, barely tired.

Ji-Hoon smiled.

"She passed."

Min-Jae turned away.

"Assign her to Team Three."

Ji-Hoon looked surprised.

"Elite team already?"

"Yes."

Min-Jae walked toward the door.

"Let’s see what she can really do."

That evening, Seo-Yeon received her first mission.

Protect a businessman at a private event.

She stood quietly near the entrance, watching the crowd.

Music played softly. Guests laughed and talked.

But Seo-Yeon stayed alert.

Then she noticed something.

A man near the corner.

Nervous.

Moving strangely.

Her eyes narrowed.

She walked toward him.

"Excuse me."

The man froze.

Seo-Yeon noticed his hand inside his jacket.

Without hesitation, she grabbed his wrist.

A small knife fell to the floor.

Security rushed in.

The man was quickly removed.

The situation ended quietly.

Later, Seo-Yeon was called upstairs.

Min-Jae sat behind his desk.

"You handled that well."

"Thank you."

"You didn’t hesitate."

"I couldn’t."

Min-Jae leaned forward slightly.

"You’ve done this before."

Seo-Yeon stayed silent.

Min-Jae didn’t push further.

"Good work."

She bowed.

As she left, Min-Jae watched her again.

She wasn’t ordinary.

Not at all.

Later that night, Min-Jae left the building.

The parking lot was quiet.

Suddenly, Seo-Yeon stepped forward.

"Boss."

Min-Jae looked surprised.

"You’re off duty."

"I noticed someone following you."

Min-Jae paused.

Just then—

A black car sped toward them.

Seo-Yeon pulled him aside quickly.

The car passed and disappeared.

Silence.

Min-Jae looked at her.

"You saved me."

"I was doing my job."

Min-Jae nodded slowly.

"From now on, you’re assigned to my personal team."

Seo-Yeon blinked.

"Yes, boss."

Far away, inside a dark room, a man watched a screen.

Seo-Yeon’s photo appeared.

"So… the Pravy Boss has a new guard."

He smiled.

"Interesting."

The rain continued falling outside.

And somewhere in Seoul…

A dangerous game had just begun. 🔥

The morning air in Seoul was cold and quiet.

Inside Pravy Group headquarters, the staff moved quickly. Phones rang, elevators opened and closed, and security teams prepared for the day’s assignments.

But today felt different.

Because Han Seo-Yeon had just been assigned to the boss’s personal team.

That meant one thing.

She would now be working directly with Kang Min-Jae.

And everyone knew how rare that was.

Seo-Yeon stood outside the top-floor office, adjusting her black jacket. She took a calm breath before knocking.

"Come in."

She opened the door.

Kang Min-Jae sat behind his desk, already reviewing files. He looked up briefly when she entered.

"You're early."

"I prefer being early, boss."

Min-Jae nodded slightly.

"Good."

He handed her a file.

"Your new assignment."

Seo-Yeon opened it carefully.

"Business trip?"

"Yes. Busan."

Seo-Yeon looked up.

"When?"

"Today."

She blinked slightly but quickly nodded.

"Understood."

Min-Jae stood up, grabbing his coat.

"We leave in thirty minutes."

Seo-Yeon followed him out.

Her first mission as his personal guard.

Thirty minutes later, they were inside a black SUV heading toward the airport.

Seo-Yeon sat beside the driver, quietly watching the road. Min-Jae sat in the back, reviewing documents.

After a few minutes, Min-Jae spoke.

"You noticed the car yesterday."

"Yes."

"How?"

Seo-Yeon hesitated.

"Experience."

Min-Jae watched her through the mirror.

"You keep your answers short."

"I don't talk much."

Min-Jae gave a faint nod.

Silence returned.

But Seo-Yeon could feel something.

Min-Jae didn’t trust easily.

And he was watching her.

At the airport, security moved quickly. Pravy Group had already arranged everything.

Within minutes, they boarded a private flight.

Seo-Yeon stood near the door, watching carefully.

Min-Jae glanced at her.

"You can sit."

"I'm fine."

"You'll get tired."

"I'm used to it."

Min-Jae didn’t argue.

Instead, he returned to his documents.

But again, he found himself noticing her.

She stayed alert.

She noticed everything.

She never relaxed.

And that meant only one thing.

She had lived a dangerous life before.

Two hours later, they landed in Busan.

The sea breeze greeted them as they exited the airport.

A second security team joined them.

Ji-Hoon walked over.

"Boss, the meeting location is ready."

Min-Jae nodded.

Seo-Yeon followed closely as they entered another SUV.

The drive took thirty minutes.

Soon, they arrived at a luxury hotel near the coast.

Seo-Yeon scanned the building carefully.

Too many windows.

Multiple exits.

Crowded entrance.

She quietly memorized everything.

Inside, the meeting was already prepared.

Several businessmen sat around the table.

Min-Jae took his seat calmly.

Seo-Yeon stood behind him.

The meeting began.

Everything seemed normal.

Until Seo-Yeon noticed something.

One of the staff members moved nervously.

Her eyes narrowed.

She watched carefully.

The man placed drinks on the table.

But his hands trembled.

Seo-Yeon stepped forward slightly.

The man reached toward Min-Jae.

Seo-Yeon grabbed his wrist instantly.

The tray fell.

A small device dropped to the floor.

Everyone froze.

Security rushed in.

The man tried to run.

Seo-Yeon blocked his path and pinned him down.

Within seconds, he was restrained.

The room filled with whispers.

Min-Jae looked at the device.

"A tracker."

Ji-Hoon frowned.

"They were trying to track your location."

Min-Jae’s expression turned cold.

"Take him away."

Seo-Yeon stepped back quietly.

Min-Jae glanced at her.

"You noticed again."

"Yes."

"You saved the meeting."

Seo-Yeon bowed slightly.

"It's my job."

But Min-Jae knew something.

She wasn’t just doing her job.

She was protecting him personally.

After the meeting, they returned to the hotel.

Min-Jae stood by the window, looking at the ocean.

Seo-Yeon stood near the door.

After a moment, Min-Jae spoke.

"You’re not an ordinary recruit."

Seo-Yeon remained silent.

"You move like someone trained for years."

She didn’t respond.

Min-Jae turned toward her.

"Who trained you?"

Silence filled the room.

Finally, Seo-Yeon answered softly.

"My brother."

Min-Jae raised an eyebrow.

"He was security?"

"No."

She hesitated.

"He was... military."

Min-Jae studied her expression.

"And now?"

Seo-Yeon looked away slightly.

"He's gone."

Min-Jae didn’t ask further.

But he understood.

There was pain behind her calm eyes.

That evening, Seo-Yeon walked through the hallway.

Her phone vibrated.

She stopped.

Unknown number.

She answered quietly.

"Hello."

A deep voice spoke.

"So... you joined Pravy Group."

Seo-Yeon’s eyes widened slightly.

"Who is this?"

"You forgot me already?"

Her expression hardened.

"You shouldn't have come here."

Seo-Yeon’s grip tightened.

"What do you want?"

"Leave the boss."

Her voice turned cold.

"No."

The man chuckled softly.

"Then things will get dangerous."

The call ended.

Seo-Yeon stood silently.

Her past had just followed her.

Later that night, Min-Jae stepped outside the hotel balcony.

He noticed Seo-Yeon standing nearby.

"You should rest."

"I'm fine."

"You never rest."

"I'm used to it."

Min-Jae looked at her carefully.

"You look worried."

She hesitated.

"It's nothing."

Min-Jae didn’t believe her.

But before he could speak—

A loud sound echoed.

A shot.

Seo-Yeon reacted instantly.

She pulled Min-Jae down.

Glass shattered behind them.

Another shot.

Security rushed in.

Chaos filled the hallway.

Seo-Yeon stayed calm.

"Sniper."

Min-Jae looked at her.

"You’re sure?"

"Yes."

Security teams searched immediately.

But the shooter had already escaped.

Silence slowly returned.

Min-Jae stood up slowly.

"You predicted danger."

Seo-Yeon didn’t respond.

Because she knew something.

This wasn’t random.

Someone was targeting Min-Jae.

And that someone…

Might be connected to her past.

Far away, inside a dark car, a man smiled.

"She's protecting him well."

He looked at a photo.

Seo-Yeon.

"Let's see how long you can protect the Pravy Boss."

The car disappeared into the night.

Back at the hotel, Seo-Yeon stood outside Min-Jae’s room.

She stayed alert.

She wouldn’t let anything happen.

Not again.

Because protecting the Pravy Boss…

Was no longer just her mission.

It had become personal.

And somewhere in the darkness…

The real enemy was getting closer.
