Part2, Part3, Part4, Part5

The first time the hallway appeared, Heeseung thought he was hallucinating from exhaustion.

It was almost 2:13 a.m.

The dorm was silent except for the faint hum of the refrigerator downstairs and the soft vibration of rain against the windows. Everyone had gone to sleep after practice. The managers had finally stopped calling. Even the city outside seemed dead.

Heeseung stepped out of his room to get water.

That was when he saw it.

The hallway.

Long.

Impossible.

The dorm corridor should’ve ended after Sunghoon’s room. Instead, beyond the familiar wall stretched another passage bathed in dark red light. Not bright red. Not warm. A suffocating crimson glow, like blood beneath skin.

The walls looked wet.

At first, Heeseung genuinely thought someone had left LED lights on. But the deeper he stared, the more wrong it became.

The hallway was too long.

Too narrow.

And there was singing.

Soft at first.

Children’s voices.

A lullaby.

His entire body locked.

He knew every inch of this dorm. They all did. There was no hallway there.

Then a memory surfaced.

Jay mentioning it jokingly over dinner two weeks ago.

“If you ever see a red hallway,” he had laughed while scrolling through his phone, “don’t walk to the end.”

The others had laughed too.

Jake claimed trainees used to spread ghost stories about the building before ENHYPEN moved in. Jungwon added that staff members avoided talking about the old dorm layout. Ni-ki had even dared Sunoo to go looking for it at night.

But now—

It was real.

The singing stopped.

Silence crashed over the hallway.

Then—

tap.

A single sound from deep inside.

Heeseung stumbled backward immediately.

Every instinct screamed at him to shut his door and pretend he never saw it.

Then something moved.

Far down the corridor.

A silhouette.

Tall.

Human-shaped.

Standing completely still under the red glow.

Heeseung’s breathing grew shallow.

“...Sunghoon?”

The figure tilted its head.

Too slowly.

Too far.

Its neck bent with a soft crack.

And then Heeseung ran.

—

The next morning, the hallway was gone.

Of course it was.

He checked three separate times.

Only a normal wall remained beyond Sunghoon’s room.

Nobody believed him.

“Hyung, you probably dreamed it,” Jake said while making coffee.

“You watch too many horror edits,” Sunoo teased.

But Jungwon looked uneasy.

“Did you hear singing?” he asked quietly.

The table went silent.

Heeseung froze.

Jungwon immediately shook his head. “Never mind.”

But later that night, Heeseung noticed Jungwon locking his bedroom door.

—

Three nights later, Heeseung received the voice message.

It came at exactly 11:47 p.m.

Unknown Number.

No.

Not unknown.

His own number.

His stomach dropped.

For several seconds he just stared at the screen while the others argued over a movie downstairs.

The timestamp made no sense.

Sent: Friday, 2:14 a.m.

Three days in the future.

A cold pulse crawled through his chest.

He pressed play.

Static burst through the speaker.

Heavy breathing.

Then—

His own voice.

Broken.

Terrified.

Crying.

“If you hear knocking tonight... don’t answer.”

The message cut off.

Heeseung’s blood turned to ice.

The sound was unmistakably him.

Not edited.

Not fake.

Every tiny breath. Every tremble in his voice.

Real.

His hands shook violently as he replayed it.

Again.

Again.

Again.

Each time, another sound became clearer beneath the static.

Knocking.

Slow.

Rhythmic.

Three knocks.

Then silence.

Three knocks.

His phone suddenly buzzed in his hand.

A text message appeared beneath the recording.

DON’T LET IT INSIDE.

Heeseung stood up so quickly the chair crashed backward.

“What happened?” Sunghoon asked.

Heeseung opened his mouth—

Three knocks echoed through the dorm.

Everyone froze.

The sound came from the front door.

Knock.

Knock.

Knock.

The movie downstairs continued playing softly.

Nobody moved.

Another knock.

This time louder.

Jay frowned. “Manager hyung?”

“No,” Heeseung whispered instantly.

Every face turned toward him.

The blood had drained completely from his face.

“No one open it.”

Jake laughed nervously. “Hyung, you’re scaring me.”

Then the voice came.

“Heeseung.”

Soft.

From behind the door.

His own voice.

Every member went silent.

“Heeseung,” it repeated. “Open the door.”

Sunoo’s expression changed immediately.

“That’s not funny.”

Nobody had moved toward the entrance.

Nobody was pranking them.

The voice outside laughed softly.

Exactly like Heeseung.

Then came the singing.

The same lullaby from the hallway.

Jungwon stood up so abruptly his chair scraped hard against the floor.

“Don’t open it,” he said.

His voice was shaking.

Too much.

As if he already knew.

The knocking became violent.

BANG.

BANG.

BANG.

The entire door rattled.

Ni-ki cursed under his breath.

Jay grabbed a kitchen knife instinctively.

“Heeseung,” the voice outside sobbed suddenly.

Crying.

Begging.

“Please let me in.”

It sounded terrified.

Human.

Real.

And somehow that made it worse.

The lights flickered.

Red.

For only a second.

But it was enough.

Because when the lights returned—

The hallway had appeared again.

Directly behind them.

The impossible red corridor stretching endlessly through the dorm wall.

The singing echoed louder now.

Closer.

And standing at the very end of the hallway—

was Heeseung.

Not the real one.

The thing in the hallway smiled too wide.

Its mouth split slowly upward.

Farther.

Farther.

Until the skin tore.

Sunoo screamed.

The apartment lights exploded.

Darkness swallowed everything.

Then came footsteps.

From inside the hallway.

Walking toward them.

One.

Step.

At.

A.

Time.

Heeseung couldn’t breathe.

The thing outside the door began pounding harder.

The thing inside the hallway kept walking closer.

And somewhere between the knocking and the singing—

his phone vibrated again.

Another voice message.

Timestamped: Tomorrow.

With trembling fingers, Heeseung pressed play.

Static crackled.

Then Jay’s voice screamed:

“DON’T LOOK AT ITS FACE—”

The audio cut into a horrible choking sound.

Then silence.

Complete silence.

Until—

A hand touched Heeseung’s shoulder from behind.

He turned automatically.

And saw himself smiling back at him in the dark.
