The room felt too quiet.
Not peaceful.
Not calm.
Just quiet in the way a storm holds its breath before it tears the sky open.
Ah-rin stood in front of her desk, staring at the small black flash drive like it might disappear if she blinked too hard.
A blue file.
A flash drive.
A familiar scent.
She knew that scent. She had memorized it long ago — and she knew exactly who it belonged to.
He hadn't said a word.
But he had left something behind.
And that was worse.
Her fingers hovered above the device for a moment before she finally picked it up. It felt heavier than it should have. Like it carried consequences instead of data.
She slid it into her laptop.
The screen flickered.
A single folder appeared.
No password.
No encryption.
Just one clean, deliberate name:
NORTH SUPPLY – INTERNAL MATERIAL LOGS
Her pulse slowed.
Then quickened.
She clicked.
Spreadsheets opened one by one — purchase orders, shipment records, quality certifications, batch numbers. She scanned automatically at first, her mind trained to filter details like muscle memory.
But then—
A company name.
Her breath caught.
Hanseong Infrastructure Co.
She froze.
No.
Her eyes moved back to the header.
Primary Supplier – Hanseong Infrastructure Co.
Her hand tightened around the mouse.
That name didn't belong here.
Not here.
Not like this.
She leaned closer to the screen as if proximity would change the letters.
Hanseong Infrastructure.
Her sister-in-law's family company.
Her eonnie's father's company.
Her throat went dry.
She clicked deeper into the files.
Inspection photos. Lab test reports. Internal comparison sheets.
A column highlighted in red.
"Density below standard requirement."
"Load-bearing capacity compromised."
"Batch inconsistency detected."
Her heart dropped.
The materials used in the north section.
The scaffolding area where the accident almost happened.
Default materials.
Supplied by Hanseong.
She grabbed her phone before she could overthink it.
She scrolled to the contact she hadn't called in weeks.
Eonnie.
The call rang twice.
Three times.
Then—
"Hello."
The familiar voice came across the line — warm, calm, unaware.
Ah-rin swallowed.
"Eonnie… it's me. Ah-rin."
A soft laugh.
"Yes, how are you, Rinrin?"
Rinrin.
The nickname made something ache in her chest.
"I'm good," Ah-rin replied automatically, even though she wasn't sure that was true. "Actually… I need some information."
There was a small pause on the other side.
"Yes, say."
Ah-rin hesitated for the first time.
How do you tell someone that their family's name just appeared in a potential corporate scandal?
How do you ask without accusing?
"Eonnie… your father's company…"
"What about it, Rinrin?"
"Who is managing it right now?"
A small shift in tone.
"Your oppa. Why?"
"No…" The word left her mouth in a whisper.
This had to be wrong.
A clerical mistake.
A forged document.
Someone trying to frame them.
Or…
Her brother.
No.
She shook her head immediately.
Not him.
Not her oppa.
He was strict, disciplined, sometimes ruthless in business — but never dishonest. Never reckless.
She had grown up watching him protect the company like it was a fragile inheritance carved from their father's bones.
He wouldn't risk it.
He wouldn't risk everything.
Right?
Her chest tightened.
Sje came back to her sense hearing her sister-in-law.
"He had taken full operational control after their father's health declined. Everyone knew that. Is there any problem? "
Ah-rin closed her eyes briefly.
"I'm here at the northern site," she began carefully. "To see the progress of the workers. But while observing, I noticed some default materials. When I checked the supplier logs…"
She forced herself to say it.
"I found out your father's company is the one supplying materials here."
Silence.
Not short.
Not casual.
Heavy.
"You mean…" her eonnie's voice came slower now, more cautious, "the materials sent from here were defaulted?"
Ah-rin's throat tightened.
"I… yes, eonnie."
A long breath on the other side.
"Ah-rin, there must be some mistake. Please check again. Your brother wouldn't do something like this, right?"
That sentence pierced her.
Your brother wouldn't do something like this.
Would he?
"I know, eonnie," she said quickly. "That's why I called you. I just wanted to confirm who's managing operations. Don't worry. I'll personally check what exactly is going on."
"You think someone altered the batches?" her eonnie asked, worry now evident. "Or tampered with the reports?"
"I don't know yet."
That was the most honest answer she had.
"I'll investigate quietly first," Ah-rin continued. "Please don't tell oppa yet."
A pause.
"Rinrin… if this is real…"
"I'll handle it," she said softly. "I promise."
Her eonnie exhaled slowly.
"Okay. Call me once you know more."
"I will."
They ended the call.
The room felt even quieter now.
Ah-rin stared at the screen again.
The spreadsheets looked different this time.
Less like numbers.
More like landmines.
She leaned back in her chair.
Wave of questions crushed her mind at a time.
Why would he give her this?
Why not report it directly?
What will he gain from this exactly?
Why leave it silently on her desk?
Unless—
He wanted her to see it first.
Before the audit.
Before the board.
Before the explosion.
Her chest tightened.
Was he protecting her?
Or giving her just enough rope to decide which side she stood on?
Her phone buzzed.
A message.
Unknown number.
She opened it.
"Audit team advanced review begins tomorrow at 9 AM. North section prioritized."
Her stomach dropped.
Tomorrow?
So this wasn't random.
The audit wasn't just about safety compliance.
It was targeted.
And someone knew.
Her mind started connecting dots rapidly.
The accident.
The advanced audit.
The defective materials.
The flash drive.
Her brother's company.
Someone wanted this exposed.
But why now?
She stood up abruptly and walked toward the large window overlooking the site.
Workers moved like ants below, unaware that their safety might have been compromised by a signature on a shipment form.
If those materials failed—
People could die.
This wasn't just business politics anymore.
This was human.
Her jaw tightened.
She went back to the laptop and opened the batch tracking log.
Each shipment had a verification signature.
Site manager approval.
Quality control confirmation.
And—
Internal authorization from Hanseong Infrastructure.
Her brother's digital signature.
Her hands began to shake slightly.
Was it forged?
Or real?
Her laptop screen reflected her face faintly.
Torn between two worlds.
Family.
Responsibility.
Truth.
Loyalty.
If she exposed this and it was real—
Her brother's reputation would crumble.
If she ignored it—
Workers could pay the price.
Her phone buzzed again.
Evan.
"Careful who you call."
Her eyes widened.
Was he monitoring her?
Or guessing?
She typed quickly.
"Stop playing games."
His reply came slower this time.
"I'm not."
She closed her eyes briefly.
This wasn't just about defective materials.
It was about power.
About who controlled the narrative before the audit team walked in.
If the audit exposed this publicly—
It would look like negligence.
If she handled it internally first—
She could contain the damage.
But someone had advanced the audit.
Who triggered it?
Was it Evan?
Or someone above him?
Or—
Her mind suddenly shifted direction.
What if this wasn't corruption?
What if someone switched the materials after shipment?
What if Hanseong sent proper batches—
And someone replaced them on-site?
Her eyes snapped back to the batch codes.
The verification stamps.
She zoomed into the digital signature.
It matched.
But digital signatures could be replicated.
Forged.
Manipulated.
She needed physical samples.
She needed lab confirmation.
She grabbed her blazer.
If the truth was buried in concrete and steel—
She would dig it out herself.
As she stepped out of her office, her phone vibrated one last time.
A final message from Evan.
"Tomorrow at 9 AM, the audit begins."
Then another.
"Tomorrow won't leave room for indecision."
Her steps slowed.
Which side?
Was it really that simple?
Family versus truth?
Or was there a third side she hadn't seen yet?
And most importantly, how does he even know this matter?
She looked at the mirror placed beside her table.
Her reflection in the mirrored wall looked older somehow.
More tired.
More aware.
She whispered to herself softly—
"I'll choose the side that protects people."
Even if it cost her everything.
The elevator doors closed.
And somewhere, in another building, someone else was watching the same clock count down to 9 AM.
The inspection was coming.
But this time—
It wasn't just the site under review.
It was blood.
Trust.
And the fragile line between love and loyalty.
& Ah-rin was standing exactly where that line could break.
To Be Continued....
