The house was alive.
Not in the way people usually mean it—not breathing, not thinking. But alive in the way sound piled upon sound until silence had nowhere left to exist.
Voices overlapped in the living room, conversations colliding and reforming without ever settling. Laughter rose and fell without rhythm, cutting into unfinished sentences and reshaping them into something new.
From the kitchen came the sharp hiss of oil—followed instantly by a shout:
"Don't touch that!"
A brief silence.
Then laughter again—louder this time.
Plates clinked. Someone complained about getting burned. Someone else mocked them for it. The noise swelled, as if the walls themselves were holding it together.
It was messy. Loud. Normal.
Kaito sat at the edge of the sofa, one leg folded beneath him, a phone hanging loosely in his hand. His thumb moved lazily across the screen, though he wasn't actually looking at anything.
It was always like this at gatherings.
Too many voices.
Too many overlapping conversations.
Too many invisible expectations—
React here. Laugh there. Say something at the right moment.
It was easier to stay at the edge.
To exist without really participating.
"Hey."
A light tap on his shoulder—just enough to pull him back.
Kaito looked up. Ren stood there, already reaching for snacks, a familiar grin on his face.
"You're doing it again," Ren said.
"Doing what?"
"That thing where you're here… but not really here."
Kaito exhaled softly. "I'm listening."
"No, you're not." Ren dropped onto the sofa beside him, stretching his arm behind his head. "You haven't reacted to anything in the last five minutes."
"Nothing interesting happened."
Ren laughed. "You really say that in a situation like this?"
"Kaito!" his mother called from across the room. "At least pretend you're enjoying yourself!"
"I am."
"Liar."
Ren leaned closer. "That's definitely a lie."
Kaito nudged him away. "Shut up."
Ren laughed again—loud, unpolished, slightly annoying.
And yet—
Strangely comforting.
A sound that filled space without asking permission. A sound that had always been there.
In the background, their fathers talked about work and repairs. Their voices were steady—grounding.
Nothing was wrong.
Nothing was unstable.
Too stable.
Kaito shifted slightly.
The feeling came suddenly.
Something crawling up his spine—not pain, not fear.
Just—
Wrong.
His gaze drifted toward the staircase.
At the edge of the room, half-sunk in shadow.
Still.
Empty.
Nothing there.
And yet—
He couldn't look away.
"…You okay?" Ren asked.
Kaito blinked. "…Yeah."
"…Really?"
A brief hesitation.
"…Yeah."
Ren studied him for a moment, then shrugged. "If you say so."
The noise returned.
But the feeling didn't leave.
Something was wrong.
And then—
THUD.
The sound tore through everything.
It wasn't loud.
But it was heavy.
Too heavy.
Not something falling.
Not something breaking.
Something else.
The room froze.
Laughter stopped.
Conversations died.
All eyes turned to the stairs.
"…Did something fall?" someone whispered.
Kaito sat up slightly. "No."
The answer came too fast. Too certain.
Everyone looked at him.
"That wasn't something falling."
Even Ren didn't joke. "…Yeah."
The air changed.
Warmth drained away, replaced by something tight and cold.
Kaito's father stood. "I'll check."
Ren's father followed. "Probably just something tipping over."
Their voices were calm.
Too calm.
They walked toward the stairs.
Their footsteps echoed louder than they should.
Kaito watched.
A strange pressure built in his chest.
"…Isn't that taking too long?" Ren muttered.
"Give it a minute," someone said.
One minute.
Then another.
Nothing.
No voices. No footsteps.
Only silence.
Not normal silence.
Wrong silence.
Kaito stood slowly. "…Dad?"
No response.
As if the words vanished before reaching anything.
Ren leaned forward. "…That's not right."
Kaito stepped toward the stairs.
Something inside him resisted.
Don't.
But he didn't know why.
Then—
Step.
A sound.
From the stairs.
Not walking.
Dragging.
Step.
The lights flickered once. Twice.
A shadow appeared.
Slowly.
Unnaturally.
Like something trying to remember how to move.
Kaito's breath stopped.
"…Dad?"
The shadow stepped forward.
And the world broke.
It was his father—
—or what remained.
From the chest up, there was nothing.
Just torn flesh and blood.
The lower half still moved.
In a way that should not exist.
Someone screamed.
Glass shattered.
The air filled with the metallic smell of blood.
Kaito couldn't move.
For a moment—
The body turned toward him.
"…run…"
The voice barely existed.
Then it collapsed.
Everything shattered.
"Get the kids out!"
Chaos exploded.
Chairs scraped.
Voices collided.
Bodies crashed into each other.
"Kaito!"
His mother grabbed his arm hard. "Don't look!"
Too late.
He already had.
Ren's mother pulled him close. "Stay with me!"
"What is happening?!" Ren shouted.
No one answered.
Because—
It was already there.
Kaito felt it.
Not a sound. Not a shape.
A presence.
Heavy.
Watching.
"Move!" his mother screamed.
They ran.
The hallway stretched too long.
The walls felt farther away.
The air grew heavy.
Breathing hurt.
Nothing was behind them.
And that—
was the worst part.
Then—
Something hit.
Invisible.
Cold.
Fast.
His mother's grip tightened for a moment.
"…Keep running."
And then—
She was gone.
Kaito stopped. "…Mom?"
No answer.
Ren's voice shook. "…Kaito…"
Don't turn around.
Run.
They burst outside.
The street was empty.
Not quiet.
Empty.
"…Where is everyone…?" Kaito whispered.
Ren grabbed his sleeve. "Don't stop."
They ran.
It was following.
Closer.
Closer.
"…Do you feel it?" Ren asked.
Kaito didn't answer.
Then—
Ren stumbled.
"Kaito—!"
"Get up!"
He stood—
And then—
Something grabbed him.
From nothing.
"Kaito—!"
A hand reached out.
"Help—!"
Kaito stepped forward.
And then—
He ran.
"I—"
His breath shattered.
"I—"
His thoughts stopped.
He couldn't turn back.
"Kaito—!"
And then—
Silence.
Kaito kept running.
Then stopped.
Not by choice.
Something held him.
Pressure.
Heavy.
Watching.
Don't turn.
But he knew.
"…Is this the end…?"
Memories surfaced.
His mother.
His father.
Ren.
His chest tightened—
Then loosened.
"…I'll see you again."
He closed his eyes.
Accepted it.
Something moved.
Right in front of him.
He didn't open his eyes.
He didn't need to.
He already knew.
And then—
