The pressure was unbearable.
Lina couldn't breathe.
It wasn't just the air—it was everything. The walls. The floor. The house itself pressing in, tightening, watching.
Her fingers clawed at the wood beneath her, but it wasn't wood anymore.
It was warm.
Alive.
"Ethan…" she gasped, her voice cracking as something inside her chest shifted—moved—like a hinge being forced open.
A sharp creak echoed from within her ribs.
She screamed.
Her back arched violently, and for a moment, she felt it—felt herself splitting, not in flesh, but in something deeper. Something that shouldn't exist.
"Lina! Stay with me!" Ethan's voice cut through the noise, panicked, desperate.
Hands grabbed her shoulders, trying to pull her away from the door—
—but the door was her.
"No—no—don't touch me!" she cried, even as she reached for him. "It's inside—Ethan, it's—"
Her words broke into a choked sob as her skin rippled.
Cracked.
Not like wounds.
Like seams.
Thin, jagged lines spread across her arms, glowing faintly beneath the surface. They pulsed in rhythm with the house—a slow, hungry heartbeat.
Thump.
The walls shuddered.
Thump.
The floor shifted beneath them.
Thump.
Lina's chest opened a fraction wider.
A dark line ran down the center of her torso, splitting her—not with blood, but with shadow.
And from within—
Something moved.
"Get away from her."
The voice was cold.
Flat.
Wrong.
Ethan froze.
Slowly… he turned.
Standing at the end of the hallway was—
Himself.
Same face.
Same height.
Same eyes.
But empty.
The second Ethan tilted his head slightly, observing Lina like she was nothing more than an object.
"A vessel shouldn't be handled so carelessly," he said.
The real Ethan stepped back, placing himself in front of Lina. "Stay the hell away from her."
The other one smiled.
Too wide.
"She doesn't belong to you."
Lina couldn't focus.
Their voices sounded distant now, like echoes underwater.
All she could feel was the opening.
It was wider now.
Inside her.
Not pain.
Not exactly.
It was worse.
It was space.
A hollow emptiness stretching endlessly, pulling, dragging—
Calling.
"Lina…"
The whisper didn't come from outside.
It came from within.
Her eyes widened.
"No…" she breathed.
"You hear it now," the voice murmured, softer, almost gentle. "You feel what you are."
Her body trembled as the darkness inside her shifted again.
Something pressed against the opening.
From the other side.
Trying to come through.
"Stop it!" the real Ethan shouted, lunging at his double.
They collided hard, slamming into the wall. The house groaned in response, as if annoyed by the disruption.
But the second Ethan didn't struggle.
He simply… allowed it.
Then leaned in close.
"You can't stop this," he whispered.
And then—
He shoved him back with inhuman force.
Ethan crashed to the ground, the breath knocked out of him.
Lina screamed again.
This time, something answered.
From inside her.
A hand—
No.
Not a hand.
Something like a hand—
Pressed against the opening in her chest from the inside, stretching her further apart.
Her body jerked violently.
"It's coming out—!" she choked.
Her vision blurred as shadows spilled from the crack in her body, thick and shifting like smoke—but heavier. Alive.
The house fell silent.
Watching.
Waiting.
"Lina!"
Ethan crawled toward her, ignoring the other version of himself.
"Listen to me," he said urgently, grabbing her face, forcing her to look at him. "You're still here. Do you hear me? You're still you."
Her eyes flickered.
For a second—
Just a second—
She saw him clearly.
"Ethan…" she whispered weakly.
"Fight it," he said. "Whatever it is—don't let it take you."
The voice inside her laughed.
A low, ancient sound.
"She cannot fight what she was made to be."
The pressure surged.
The opening widened.
And then—
Something pushed through.
Lina's scream cut off abruptly.
Her body went still.
Too still.
Ethan froze.
"Lina…?"
Slowly… painfully slowly…
Her head tilted.
But not naturally.
Not human.
Her lips parted.
And when she spoke—
It wasn't her voice.
"Finally…"
The word echoed unnaturally, layered with something deeper.
Older.
Hungry.
Her eyes—
No.
Not her eyes anymore.
They were darker now.
Endless.
Looking at him like he was nothing.
Ethan's blood ran cold.
"Lina…?" he whispered again, but he already knew.
The thing inside her smiled.
And the house—
The house shuddered in delight.
"Open," it said softly.
And Lina's body obeyed.
