Episode 2

The Investigator and the Siren

Sleep never came easily to Yoo Hae-rin.

Not after the photograph.

Not after the message written in blood-red ink.

You’re next.

The words stayed in her mind long after midnight, echoing through the silence of her penthouse like a warning she couldn’t escape.

Hae-rin stood barefoot near the kitchen counter, staring at the photograph again. Three dead men stood beside her in smiling perfection, unaware of what their futures held.

Or perhaps someone had planned those futures from the beginning.

Her fingers tightened around the picture.

Someone wanted her afraid.

Someone wanted her blamed.

A sudden vibration pulled her attention away.

Unknown Number.

She hesitated before answering.

“…Hello?”

For several seconds, only silence answered her.

Then a distorted male voice whispered:

“How long do you think you can keep pretending?”

The line disconnected immediately.

Hae-rin’s heartbeat slowed instead of racing.

Fear was dangerous.

Fear made mistakes.

And Yoo Hae-rin could not afford mistakes anymore.

⸻

The next morning, Royal Auction House was drowning in reporters.

Camera flashes exploded outside the entrance while journalists shouted questions the moment Hae-rin’s black car arrived.

“Miss Yoo! Did you know Kang Min-ho personally?”

“Are the rumors true?”

“Did you benefit from his insurance payout?”

Her bodyguards pushed through the crowd while Hae-rin remained calm behind dark sunglasses, refusing to answer a single question.

But the moment she stepped inside the building—

She stopped walking.

Because he was there.

Lee Tae-jun stood near the center lobby waiting for her, dressed in a black suit that matched the cold expression on his face.

Sharp eyes.

Controlled posture.

A man impossible to intimidate.

Unfortunately for him—

Hae-rin enjoyed impossible things.

“You’re becoming difficult to avoid,” she said softly while removing her sunglasses.

Tae-jun watched her carefully.

“And you’re becoming difficult to defend.”

A faint smile curved her lips.

“That sounds almost personal.”

“It’s my job.”

“No,” Hae-rin replied quietly as she stepped closer. “If it were only your job, you wouldn’t keep looking at me like that.”

The tension between them tightened instantly.

Tae-jun hated how composed she remained under pressure. Most suspects either panicked or overexplained themselves.

Yoo Hae-rin simply watched him like she already understood every thought crossing his mind.

Dangerous woman.

“Three dead men,” Tae-jun said coldly. “All connected to you.”

“And yet I’m still free.”

“You think that makes you innocent?”

Hae-rin’s eyes darkened slightly.

“I think it makes you frustrated.”

For the first time, Tae-jun stepped closer instead of away.

Close enough to notice the faint scent of expensive perfume mixed with wine lingering around her.

Close enough to realize how effortlessly she invaded a person’s senses.

“You enjoy this, don’t you?” he asked quietly.

“Enjoy what?”

“The attention. The obsession.”

Hae-rin tilted her head slightly.

“And if I do?”

Their eyes locked.

Neither moved.

Neither looked away.

The air between them felt heavier now—less like an interrogation and more like something dangerous slowly unfolding beneath the surface.

Then suddenly,

Tae-jun grabbed her wrist.

Fast.

Unexpected.

Hae-rin’s breath caught softly at the sudden contact.

“Tell me the truth,” he said in a low voice. “What really happened to those men?”

For one brief moment, the calm mask she wore cracked.

Pain flashed through her eyes.

Real pain.

But it disappeared just as quickly.

“You’re asking the wrong person,” she whispered.

Before Tae-jun could respond, his phone rang loudly.

The moment he answered, his expression changed instantly.

Another body had been found.

And this time,

The victim had a recent photograph of Yoo Hae-rin in his wallet.

Episode 3

The fourth victim was found inside a private villa on the outskirts of the city.

Male.

Thirty-eight.

Wealthy.

Dead for less than six hours.

And once again, there were no signs of violence.

The crime scene felt disturbingly peaceful — soft jazz still playing through hidden speakers, a half-finished drink resting beside the couch, and expensive perfume lingering faintly in the air.

Lee Tae-jun stood silently near the body while investigators moved around him.

“Cause of death is still unclear,” Detective Ryu reported. “But there’s something else.”

He handed Tae-jun a photograph.

The victim was smiling beside Yoo Hae-rin at a charity gala held two months earlier.

Tae-jun’s jaw tightened.

Again.

Always her.

“Where is she now?” he asked coldly.

“At Royal Auction.”

Of course she was.

⸻

Hours later, Tae-jun arrived at the exclusive after-party hosted by Royal Auction House.

Luxury filled every corner of the penthouse ballroom — crystal glasses, dim golden lights, soft music, and people rich enough to hide crimes behind money.

But the moment Hae-rin entered the room—

Everything else disappeared.

She wore a dark red satin dress that hugged her figure elegantly, her black hair falling loosely over one shoulder. Men watched her openly while women whispered behind forced smiles.

She looked untouchable.

And somehow, that only made Tae-jun more suspicious.

Hae-rin noticed him immediately.

“You’re starting to appear everywhere I go,” she said softly as he approached.

“Another man is dead.”

Her expression didn’t change.

“Then perhaps you should find the real killer.”

“You knew him.”

“I know many people.”

“That’s not an answer.”

Hae-rin lifted a champagne glass to her lips slowly, her eyes never leaving his.

“You ask questions like you already want me guilty.”

“And you answer like you enjoy the game.”

A faint smile appeared.

“Maybe I enjoy you.”

The words landed harder than they should have.

For a second, Tae-jun forgot the noise around them. Forgot the investigation. Forgot the body waiting at the crime scene.

All he noticed was her voice.

Her eyes.

The dangerous calm surrounding her.

Hae-rin stepped closer until only a small distance remained between them.

“You know what people say about me, Investigator Lee?” she whispered.

“That you ruin every man who gets close to you.”

Her lips curved slightly.

“And yet you keep coming back.”

Tae-jun grabbed her arm before he could stop himself.

The movement was sudden enough to make nearby guests glance toward them.

His voice lowered dangerously.

“If you’re playing with me, Yoo Hae-rin, it’ll end badly for you.”

Instead of fear, amusement flickered across her face.

“And if I’m not playing?”

Their bodies were close enough now for him to feel the warmth of her skin beneath the silk fabric.

Close enough to become a mistake.

Tae-jun knew he should let go.

But he didn’t.

Something about her pulled people in like gravity — beautiful, impossible, destructive.

For the first time in years, Lee Tae-jun felt emotionally off balance.

And Yoo Hae-rin noticed immediately.

That was the truly dangerous part.

⸻

Later that night, Tae-jun returned home exhausted, only to find an unmarked package waiting outside his apartment door.

Inside was a flash drive.

One video file.

No sender.

No message.

His expression darkened as he pressed play.

The screen flickered briefly before revealing security footage recorded inside a hotel hallway weeks earlier.

A man stumbled drunkenly toward his suite.

Behind him—

Yoo Hae-rin appeared on camera.

Alive.

Smiling.

Following the victim into his room only hours before his death.

Rain poured heavily over Seoul, turning the streets outside Royal Auction House into blurred reflections of neon lights and passing headlights.

Across the road, Midnight glowed quietly beneath the storm.

It was the only place Yoo Hae-rin could still breathe without pretending.

The moment she entered the bar, conversations softened.

Some customers stared openly.

Others whispered behind lowered glasses.

Everyone knew her face now.

The woman connected to too many deaths.

Hae-rin ignored the attention and walked toward the private booth near the back of the bar.

Waiting there were the only two people she trusted completely.

Her best friends.

Jung Seo-ah sat comfortably against the leather booth, camera beside him and editing files open on his laptop. As Royal Auction’s event photographer, he spent enough time around Hae-rin to understand the difference between her public mask and the exhausted woman beneath it.

Beside the counter stood Hwang Sook-ji, owner of Midnight. Sharp-tongued, fearless, and fiercely protective of the people she cared about.

Especially Hae-rin.

“You’re late,” Sook-ji said softly while pouring whiskey into a crystal glass.

“Reporters followed me again,” Hae-rin replied, slipping off her coat.

glanced toward the rain-covered windows.

“They’re still outside.”

“Of course they are.”

Hae-rin sat down heavily beside him, exhaustion finally slipping through her elegant composure.

Without a word, Seo-ah gently pulled the whiskey glass away before she could drink too quickly.

“That’s your third one this week,” he muttered.

Hae-rin looked at him tiredly. “You count now?”

“You stop sleeping now.”

Sook-ji smirked faintly.

“You two sound married.”

“We sound stressed,” Seo-ah replied immediately.

But the tension eased slightly after that.

Only around these two could Hae-rin allow herself to look tired.

Human.

For a few quiet minutes, none of them spoke. Rain tapped softly against the windows while jazz music played low in the background.

Then Sook-ji finally asked the question both of them had been avoiding.

“Are you scared?”

Hae-rin stared down at the untouched whiskey for several seconds.

“…I think I’m starting to be.”

The honesty in her voice made both of them go silent.

Because Yoo Hae-rin never admitted fear Seo-ah ‘s expression softened slightly as he leaned back against the booth.

“You know we’re on your side, right?”

Hae-rin looked at him quietly.

Even now, with the city turning against her, they stayed.

That alone terrified her more than loneliness.

“People around me keep dying,” she whispered.

Sook-ji crossed her arms. “And yet somehow you’re still more worried about everyone else.”

“That’s because she blames herself for things she didn’t do,” Seo-ah said quietly.

Hae-rin looked away immediately.

Which was answer enough.

A silence settled between the three best friends—heavy, familiar, honest.

Then suddenly—

Her phone vibrated against the table.

Unknown Number.

Again.

Hae-rin’s fingers froze slightly.

noticed immediately. “Another message?”

She unlocked the screen slowly.

One sentence appeared:

“The investigator will destroy you before I do.”

Sook-ji swore quietly beneath her breath.

Seo-ah‘s jaw tightened instantly.

“This person is escalating,” he muttered.

Before Hae-rin could respond—

The entrance bell rang softly.

And the atmosphere inside Midnight changed immediately.

Standing near the doorway, rainwater dripping slowly from his dark coat, was Lee Tae-jun.

His sharp eyes scanned the room once before landing directly on Hae-rin.

Then Seo-ah sitting beside her.

Then Sook-ji standing protectively nearby.

For one brief second, something unreadable crossed Tae-jun’s face.

Not anger.

Something quieter.

Something dangerously close to jealousy.

Sook-ji noticed instantly and sighed softly under her breath.

“Well,” she murmured, “this night just became worse.
