The office felt different that morning.
Not because anything had changed on the surface—
But because something had shifted beneath it.
The board still held the same faces.
Victims arranged in careful order.
Names written beside them.
Dates circled in red.
Yet the way the team looked at it had evolved.
They were no longer searching randomly.
They were narrowing in.
Su Young sat at her desk, her laptop open, multiple windows layered across the screen.
Data from different sources overlapped:
Consultation centers.
Service records.
Client registrations.
Each entry looked ordinary on its own.
But together—
They formed something else.
Ara walked over, holding a cup of coffee.
"Any progress?"
Su Young didn't look away from the screen.
"Not exactly progress," she said.
Ara leaned slightly closer.
"What does that mean?"
"It means I'm seeing something," Su Young replied, "but I don't know what it leads to yet.
Ara took a sip of her coffee.
"That's still something."
Su Young nodded faintly.
She clicked into another dataset.
"Look at this," she said.
Ara set her cup down.
Rows of names filled the screen.
"Registration records?" Ara asked.
"Yes."
"From the consultation centers?"
"All of them."
Ara scanned through.
"Nothing unusual."
"That's what I thought too."
Su Young tapped lightly on the keyboard.
The screen shifted.
Highlighted entries appeared.
"These," she said.
Ara frowned slightly.
"What about them?"
"They're incomplete."
"Incomplete how?"
"Each of these entries was accessed more than once," Su Young explained. "But the follow-up data is missing."
Ara looked closer.
"So someone opened the records…"
"…but didn't finish processing them," Su Young completed.
Ara straightened.
"That doesn't make sense."
"Exactly."
In a system like that, every action leaves a trace.
Access.
Modification.
Completion.
But here—
Something interrupted the process.
Repeatedly.
Ara crossed her arms.
"How many?"
"Not a lot," Su Young replied.
"Enough to notice?"
"…yes."
That was the problem.
Too few to be obvious.
Too consistent to ignore.
Kang Min approached, having overheard part of the conversation.
"What did you find?"
Su Young turned slightly.
"A pattern."
He waited.
"Not in the victims directly," she continued, "but in the data around them."
Ara gestured toward the screen.
"These entries were accessed, but not completed."
Kang Min looked at the list.
"Dates?"
Su Young pulled them up.
"They align… loosely."
"Loosely?" Kang Min repeated.
"Close to when each victim last visited these places."
That drew his attention fully.
"Show me everything."
Su Young expanded the dataset again.
More information appeared.
Time logs.
User access points.
Partial records.
Kang Min studied it carefully.
"Who accessed them?"
Su Young shook her head.
"That's the strange part."
"What do you mean?"
"The user ID isn't consistent," she said. "Different logins. Different terminals."
Ara frowned.
"So it's not one person?"
"Not directly," Su Young replied.
"But the pattern suggests otherwise."
Kang Min understood.
"Someone is masking their access."
Su Young nodded.
"Or using different entry points."
Bong Soo walked over, glancing at the screen.
"…so we have someone going through records but not finishing the job?"
"Something like that," Ara said.
Bong Soo scratched his head.
"Why not just finish it?"
Su Young leaned back slightly.
"That's what makes it interesting."
Ara added quietly,
"It means the goal isn't the record itself."
Kang Min looked at both of them.
"It's the information inside it."
Later — Conference Room
A meeting had been called.
Not a large one.
Just the core team—
And one more.
Prosecutor Lee Tae Jun walked in with his usual composed demeanor.
He greeted them with a polite nod.
"Good morning."
"Good morning," Ara replied.
Kang Min gestured toward the table.
"We've found something."
Tae Jun took a seat.
"I'm listening."
Su Young connected her laptop to the screen.
The data appeared again.
She began explaining.
"Across multiple service centers connected to the victims, we found a small set of irregular entries."
Tae Jun leaned slightly forward.
"In what way?"
"They were accessed more than once," Su Young said, "but the processes were never completed."
He considered that.
"System error?"
"Unlikely," she replied.
"Why?"
"Because it repeats in different locations," Ara said.
Tae Jun nodded.
"That suggests intent."
Kang Min spoke,
"Someone is looking into these people."
Tae Jun's expression remained steady.
"Before they become victims."
That line hung in the room.
Not heavy—
But significant.
Bong Soo shifted slightly.
"So… the killer checks them first?"
Ara answered,
"That's one possibility."
Tae Jun folded his hands.
"What kind of information do these records contain?"
"Basic details," Su Young said.
"Names, contact information, sometimes personal notes depending on the service."
He nodded.
"That's enough to identify and track someone."
Kang Min glanced at him briefly.
"Exactly."
Tae Jun leaned back slightly.
"This is good work."
Simple.
Direct.
No exaggeration.
Just acknowledgment.
Ara continued,
"It doesn't give us a name yet."
"But it gives us behavior," Tae Jun replied.
Kang Min looked at him.
"Go on."
Tae Jun spoke calmly.
"Whoever this is, they don't act randomly."
"They gather information first."
"They verify."
"And only after that—"
He stopped short of finishing.
But everyone understood.
Bong Soo exhaled slowly.
"That's… organized."
"Yes," Tae Jun said.
Ara added,
"And careful."
Su Young looked back at her screen.
"There's something else."
Everyone turned toward her.
"These incomplete entries—"
She pointed at the timestamps.
"They don't happen at random times."
Kang Min stepped closer.
"When?"
"Late hours," she said.
"Or periods when activity is low."
Tae Jun nodded slightly.
"That reduces the chance of being noticed."
Ara looked at him briefly.
"You've handled cases like this before?"
He met her gaze.
"Not exactly like this."
A small pause—
natural, not forced—
"But patterns like this exist in organized offenders."
Kang Min absorbed that.
"Someone who prepares before acting.
Everyone nodded to themselves.
"Yes."
Elsewhere — Ha Eun
Ha Eun sat at her desk in the newsroom.
Her notes were spread out again.
The same location circled.
The consultation center.
She tapped her pen lightly against the paper.
"…something's off."
She couldn't prove it.
But she couldn't ignore it either.
Her colleague glanced over.
"You're still on that story?"
"Yes."
"Didn't your editor tell you to drop it?"
Ha Eun smiled faintly.
"He did."
"And?"
"I'm just… organizing my notes."
The colleague shook his head.
"You're not letting it go, are you?"
"No."
She wasn't.
Not when something didn't sit right.
She looked at the address again.
The building.
The staff.
The responses.
Everything had been normal.
Too normal.
That was what bothered her.
Back at CID
The meeting continued.
They discussed possibilities.
Not conclusions.
Kang Min stood near the board again.
"This tells us one thing," he said.
Ara looked at him.
"He chooses."
Bong Soo added,
"Not randomly."
"Carefully," Su Young said.
Tae Jun nodded.
"That narrows your scope."
Kang Min turned slightly.
"But not enough."
"Not yet," Tae Jun replied.
He stood up.
"If you continue along this line, you'll get closer."
Ara watched him.
"Thank you."
He gave a small nod.
"That's what I'm here for."
And with that—
He left.
No suspicion.
No tension.
Just a prosecutor doing his job.
Later That Day
The team returned to their desks.
Work resumed.
Su Young kept digging into the anomaly.
Ara reviewed victim timelines again.
Bong Soo tried to connect patterns out loud.
Kang Min observed everything quietly.
The case hadn't opened up yet.
But it had shifted.
Slightly.
And sometimes—
That was all it took.
