Episode 1

If You Love Her, You Die

The man died at exactly 2:13 a.m.

By sunrise, the news had already spread through every major media outlet. Another wealthy heir found dead inside a luxury hotel suite. No signs of struggle. No visible injuries. Just a peaceful expression frozen on his face like he had fallen asleep beside someone he trusted.

Beside the bed sat a half-empty glass of expensive wine.

And on the table—

A photograph of Yoo Hae-rin.

The woman everyone whispered about.

The woman men couldn’t stay away from.

The woman whose lovers never seemed to survive.

⸻

Rain poured heavily over the city as black luxury cars lined the entrance of Royal Auction House later that evening.

Inside, the atmosphere remained elegant despite the scandal surrounding Hae-rin’s name. Wealthy socialites laughed beneath crystal chandeliers while millions exchanged hands over rare paintings and jewelry.

To the public, this world looked glamorous.

But beneath the polished smiles lived greed, obsession, and secrets powerful enough to destroy lives.

At the center of the auction stage stood Yoo Hae-rin herself.

Beautiful.

Cold.

Untouchable.

Her black dress wrapped around her like silk shadows while diamond earrings shimmered beneath the lights. Every movement she made was graceful enough to capture the entire room without effort.

“Five million.”

“Six million.”

“Eight million.”

Her voice flowed smoothly through the hall, calm and seductive, controlling the attention of every man watching her.

None of them noticed the reporters gathering outside.

None of them noticed the police vehicles parked across the street.

And none of them noticed the man quietly observing her from the back of the room.

Lee Tae-jun.

Elite investigator.

Special Investigations Unit.

A man known for destroying perfect lies.

Tae-jun studied Hae-rin carefully as she continued the auction without the slightest sign of panic. Most innocent people trembled under suspicion.

She looked perfectly composed.

That bothered him.

“She’s either innocent,” Detective Ryu muttered beside him, “or terrifyingly good at pretending.”

Tae-jun said nothing.

Because the moment Yoo Hae-rin lifted her eyes toward the crowd—

She looked directly at him.

As if she already knew who he was.

For one brief second, the noise inside the auction hall disappeared beneath the tension between them.

Then Hae-rin smiled.

Small.

Elegant.

Dangerous.

And somehow, Tae-jun immediately understood why men ruined themselves for her.

⸻

Later that night, the rain became heavier.

Hae-rin returned to her penthouse overlooking the glowing city skyline. The silence inside felt almost unnatural after hours of cameras and whispers.

She removed her diamond earrings slowly before walking toward the kitchen island.

That was when she noticed it.

An envelope resting neatly on the marble counter.

Her expression darkened instantly.

No one should have been inside her home.

Carefully, she opened it.

Inside was a single photograph.

A picture of her standing beside all three dead men.

Across the photograph, someone had written in red ink:

You’re next.

For the first time that night—

Yoo Hae-rin looked afraid.

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.
