When I opened my eyes, the right side of the bed was empty. The sheets had already gone cold, and for a few seconds, I wondered if the previous night had been nothing more than a dream.
Then I saw the vast bedroom.
I remembered my new surname.
I didn’t get up right away. Instead, I sat there, studying a room that still didn’t feel lived in. It was strange to share a life with someone whose existence barely left any trace behind.
His side of the bed was perfectly made. The towel was gone, and the wardrobe remained closed. If I hadn’t felt the slight dip in the mattress during the night, I would have sworn no one else had slept there.
The silence was different from the one in my old home.
It wasn’t peaceful.
It was disciplined.
Not a single door slammed by accident. No voices echoed through the corridors. Even the wind seemed unwilling to disturb the order that ruled this mansion.
I took a deep breath.
The air smelled of polished wood and freshly laundered linen. Everything was so immaculate that it was difficult to believe people actually lived there.
Slowly, I lowered my feet to the floor.
The marble was cold.
The instant my skin touched it, I caught my breath. My body reacted before my mind did.
For a brief moment, I found myself expecting someone to open the door without knocking.
A voice announcing another tradition.
Another ceremony.
Another trial I had yet to learn.
Nothing happened.
Only silence.
Even so, it took several long seconds before I convinced myself I was allowed to stand.
I walked slowly toward the window.
The mountains were still veiled beneath a thin layer of morning mist. From up there, the world looked motionless, as though the estate had been cut off from everything beyond it.
For a moment, I imagined the road leading down to the main gate.
It was the same road I had taken to arrive here.
Yet now it no longer looked like an entrance.
It looked like a road no one ever left.
I rested my forehead against the glass.
It was freezing.
I welcomed the sensation.
It was the first thing that had felt completely real since waking.
—
Three soft knocks broke the silence.
They didn’t wait for an answer.
The door opened with the same quiet precision that seemed to govern everything inside the mansion.
Amane entered carrying a silver tray. Resting upon it were a cup of tea, a flawlessly arranged breakfast, and a small notebook bound in black leather.
As always, her uniform was immaculate.
Not a wrinkle.
Not a single strand of hair out of place.
She placed the tray on the table without making the slightest sound.
“Good morning, Lady Zoldyck.”
I still wasn’t used to hearing that surname attached to me.
Amane seemed to notice my hesitation but chose not to comment on it.
“Master Silva has instructed me to guide you through the estate during the coming weeks.”
It didn’t sound like an offer.
Nor an order.
Simply something that would happen.
After a brief silence, I asked,
“Guide me… how?”
She gave a small nod.
“Every household has its rules. The Zoldyck family is no exception.”
She picked up the notebook but didn’t open it.
It was obvious she knew every word inside by heart.
“My duty is to ensure that you learn them.”
As she spoke, she adjusted the edge of the tablecloth by barely a few millimeters.
It was such a small movement.
Yet it told me that even the smallest imperfection was corrected immediately within these walls.
“The first rule is punctuality.”
Her voice remained as calm as ever.
“The Head of the Family’s schedule allows no delays.”
I didn’t ask what happened to those who arrived late.
Something about the calm certainty in her voice suggested no one ever dared find out.
Amane continued.
“Family meals are mandatory whenever the Head of the Family summons them.”
“And if someone doesn’t wish to attend?”
For the first time since entering the room, she paused.
She wasn’t searching for an answer.
She was deciding how much she could say.
“That doesn’t happen.”
The simplicity of her response was more unsettling than any threat could have been.
She placed the notebook back onto the tray.
“There are areas of the estate accessible only to certain members of the family.”
“How will I know which ones?”
“I will show you.”
Nothing more.
I understood exactly what she meant.
Don’t try to find out on your own.
She walked toward the door.
“If you ever find a locked door…”
She paused.
“Do not attempt to open it.”
I watched her carefully.
“What’s behind them?”
For several seconds she remained completely still.
It was the first time she seemed uncertain.
When she finally answered, her composure hadn’t changed.
“If the family decides you should know, someone will tell you.”
—
When Amane finished explaining the mansion’s most basic rules, silence settled between us once again.
“Is there anything else?” I asked.
“You may walk through the gardens.”
I looked up.
“I’m allowed outside?”
“The gardens are part of the estate. You may remain there as long as you stay on the marked paths.”
I nodded.
She turned the doorknob.
Before leaving, she added one final thing.
“There is one rule that isn’t written anywhere, Lady Zoldyck.”
She lifted her eyes ever so slightly.
“No one in this house asks questions out of curiosity.”
A brief pause followed.
“They ask only when they are prepared to accept the answer.”
The door closed softly behind her.
And for the first time since waking, I realized that surviving inside this family would require far more than memorizing its rules.
—
Amane led me to one of the mansion’s side entrances.
The moment I stepped outside, the air changed.
It was colder.
Cleaner.
I breathed deeply.
For the first time since arriving, the scent of polished stone and varnished wood gave way to damp earth and towering pine trees.
The gardens stretched endlessly before me.
They hadn’t been designed to impress.
They had been designed to remain untouched.
Stone paths wound through ancient trees, quiet ponds, and perfectly trimmed hedges. Everything seemed to grow exactly where someone had decided it should.
Even nature obeyed.
Amane inclined her head.
“You may remain here until luncheon.”
Without another word, she returned inside.
I watched the door close behind her.
For the first time since arriving…
I was completely alone.
Or so I wanted to believe.
I wandered without destination.
I simply needed to put some distance between myself and those walls.
The silence here was different.
Birds still sang.
The wind stirred the branches.
Leaves crunched beneath my shoes.
Small sounds.
Ordinary sounds.
Human sounds.
Eventually, I reached an old stone bench hidden beneath several towering trees.
Only a corner of the mansion’s roof remained visible through the branches.
I sat down.
Closed my eyes.
Only for a moment.
The peace lasted no more than a few seconds.
When I opened them again…
I hadn’t heard anything.
No footsteps.
No snapping branches.
Nothing.
And yet…
I felt watched.
Slowly, I turned my head.
Trees.
Mountains.
An empty path.
I stayed perfectly still.
Waiting.
Nothing happened.
I forced a bitter smile.
I’m imagining things.
At least, I tried to believe I was.
A crow crossed the sky.
The leaves rustled once more.
The feeling returned.
Stronger.
As though unseen eyes followed every movement I made.
I stood.
Scanned the path.
No servants.
No guards.
Not even Amane.
Yet my body still reacted as though someone stood directly behind me.
I folded my arms tightly across my chest.
The problem wasn’t knowing I was being watched.
It was not knowing from where.
Or by whom.
Or for how long.
The mansion had countless windows.
But I was beginning to suspect…
It also had eyes.
—
I kept walking.
The path sloped gently downhill between the trees. White flowers I didn’t recognize swayed quietly in the breeze.
Eventually, it led to a small clearing where another stone bench rested beneath an enormous tree.
I sat.
From there, only a sliver of the mansion’s roof could still be seen.
It was enough.
Far enough away to pretend the mansion couldn’t reach me.
I leaned back.
Closed my eyes.
Only for a few seconds.
Then it happened.
It wasn’t a sound.
It was the absence of one.
I opened my eyes.
The birds had stopped singing.
The wind no longer moved the branches.
Even the water in the nearby pond seemed to flow with unnatural stillness.
I frowned.
Looked around.
No one.
I resumed walking.
This time, a little faster.
Leaves crunched beneath my shoes.
Or so I thought.
Because a moment later…
I heard another crunch.
Heavier.
As though something had stepped exactly where I had.
I stopped.
The sound stopped too.
I waited.
Nothing.
Slowly, I turned around.
Trees.
Bushes.
Shadows.
A chill crept down my spine.
I walked again.
Crunch.
I froze.
Silence.
The air felt different now.
Heavier.
As though the entire forest were holding its breath.
I couldn’t explain why.
I simply…
Knew someone was watching me.
Not from one place.
From everywhere.
My eyes swept across the treetops.
Then the path.
Then the undergrowth.
Nothing.
Still, my heart beat faster with every step.
Then I saw them.
Footprints.
Enormous.
Deeply pressed into the damp earth.
I crouched instinctively.
They weren’t human.
Nor did they belong to any animal I’d ever seen.
Five clawed toes.
Far too large.
Another shiver forced me back to my feet.
A few steps farther ahead, I noticed deep gouges carved into the bark of a tree.
The scratches stretched from nearly two meters above the ground all the way down to its roots.
As though something had sharpened its claws there.
A knot tightened in my stomach.
I should go back.
I turned around.
And then…
I saw it.
At first, I mistook it for a boulder.
A massive dark shape standing silently among the trees.
Then it breathed.
My entire body froze.
The creature stepped into the light.
It was a dog.
No…
Dogs weren’t supposed to be that large.
Its body was enormous, muscular, covered in thick black fur. Its head was massive, its fangs visible even with its mouth closed.
But it was its eyes that stole the air from my lungs.
There was no anger in them.
No curiosity.
Only complete calm.
The quiet confidence of a predator that knew it never needed to hurry.
I took one step backward.
It took one forward.
The blood drained from my face.
I didn’t run.
Something deep inside me understood that would be a mistake.
But I couldn’t move either.
The enormous beast continued approaching.
Slowly.
Silently.
Every footstep seemed to make the ground tremble beneath me.
When it stood barely a meter away, it lifted its nose.
It sniffed the air.
Then…
It sniffed me.
I held my breath.
I could feel its warm breath against my hands.
I thought about my grandfather.
I thought about Killua.
I thought this would be my first…
and last…
walk through the estate.
The seconds stretched endlessly.
The beast walked slowly around me.
One full circle.
Then another half.
As though inspecting me.
I couldn’t understand what it was doing.
I only knew that if it decided to attack…
I wouldn’t survive.
My heart pounded so loudly I was certain it could hear it.
I never looked away.
Not because I was brave.
But because fear had left me incapable of moving.
The creature stopped in front of me once more.
For a long moment…
Neither of us moved.
Then…
It looked away.
With complete calm, it turned around, walked a short distance, and lay down in the grass.
It was still watching me.
But it no longer seemed interested in approaching.
I didn’t understand.
Not why I was still alive.
Not why the beast had walked away.
Not why I had the impossible feeling that…
Somehow…
I had just been judged.
If a creature like that roamed freely through these gardens…
What kind of family had I married into?
—
It took several minutes before I convinced myself to return.
Every few steps, I glanced over my shoulder.
The path remained empty.
Yet the feeling of being followed never disappeared.
When the mansion finally emerged between the trees, relief washed over me so suddenly I almost felt ashamed.
The towering stone walls no longer resembled a prison.
They looked like shelter.
I looked up.
Dozens of windows reflected the midday sunlight.
They all appeared identical.
Until one caught my attention.
A second-floor window.
Behind the glass, I thought I saw someone standing perfectly still.
I couldn’t make out a face.
Only the silhouette of someone tall.
Watching me.
I blinked.
A cloud drifted across the sun.
When the light returned…
The window was empty.
I stared for several more seconds.
It must have been my imagination.
I lowered my gaze and continued toward the entrance.
I never knew…
It hadn’t been.
—
Silva stood silently before the window.
He hadn’t looked away from the gardens since Amane escorted the young woman outside.
Several meters behind him, a butler waited patiently.
“Should we inform Master Killua?”
Silva continued watching the path.
The young woman had just disappeared beneath the mansion’s front portico.
Only then did he answer.
“There is no need.”
“And Mike?”
Silva glanced briefly toward the forest.
The enormous dog had already left the clearing.
“He did not consider her a threat.”
The butler remained silent.
So did Silva.
After several long moments, he finally spoke again.
“Fear reveals more about a person than any conversation ever could.”
He turned away from the window.
“We will continue observing her.”
Then he left the room.
—
A butler intercepted me before I reached the main entrance.
“Lady Zoldyck, luncheon will be served in a few minutes.”
I nodded quietly.
I didn’t ask how long he had been looking for me.
Nor whether he had witnessed what had happened in the gardens.
I was beginning to understand that inside this mansion…
Some questions were destined never to receive answers.
I returned inside.
The change was immediate once again.
The air regained its familiar scent of polished wood and ancient stone.
The disciplined silence returned, as though the forest lay miles away instead of just beyond a single door.
As I walked through the corridors, I couldn’t help glancing toward every second-floor window.
All of them were empty.
Even so…
The feeling of being watched remained.
The dining room was every bit as imposing as the rest of the mansion.
A long table of dark wood stretched across the room, laid with flawless precision.
Every fork.
Every plate.
Every glass.
Perfectly aligned.
The members of the family arrived one after another.
No one commented on my absence.
No one asked where I had been.
No one mentioned the enormous beast waiting among the trees.
Conversation was scarce.
In truth, it barely deserved to be called conversation at all.
Only a few words exchanged when absolutely necessary.
The sound of porcelain touching the table filled the silences no one seemed interested in breaking.
I ate enough not to attract attention.
I couldn’t remember the taste of the food.
My thoughts remained trapped in the garden.
In those footprints.
That breathing.
