Eva woke sometime after midnight to the sound of whispering.

Not human whispering.

Softer.

Like silk dragging across stone.

For one deeply confusing moment, she forgot where she was.

Then she opened her eyes and remembered she had accidentally signed a magical blood contract with the God of Death and was currently sleeping inside a palace built over a river full of screaming souls.

Which honestly explained quite a lot.

The fire in the black marble hearth had burned low. Pale silver light spilled through the enormous windows overlooking the Underworld below. The palace corridors beyond her chamber walls remained completely silent.

Too silent.

Eva sat up slowly beneath the heavy blankets, pushing tangled curls away from her face.

The whispering came again.

She frowned.

“…Hello?”

Nothing answered.

Wonderful.

Exactly the sort of response she had hoped for.

Eva swung her legs carefully off the bed and reached for the small dagger hidden beneath her pillow. The weapon looked deeply unimpressive compared to the magical horrors she had encountered recently, but holding it still made her feel marginally less helpless.

The whispering shifted toward the doorway.

Eva narrowed her eyes.

Something moved beneath the door.

Not feet.

Shadow.

Thin black tendrils slowly slipped across the floorboards, curling through the silver moonlight like smoke searching for warmth.

Eva froze.

The shadows stopped too.

For several long seconds, neither moved.

Then one of the tendrils crept forward another inch.

Very slowly.

Almost cautiously.

Eva stared at it in disbelief.

“…Am I being investigated by darkness?”

The shadow immediately retreated beneath the door.

Silence.

Then—

A quiet thud from the hallway outside.

Eva frowned harder.

Against every survival instinct she possessed, she crossed the room and opened the door.

The corridor beyond stood empty.

At least, empty in the traditional sense.

No servants.

No guards.

No visible monsters.

Blue fire flickered faintly inside the iron wall lanterns, casting long shadows across black stone floors.

And at the far end of the corridor stood Acheron.

Of course he did.

Eva leaned against the doorway, arms crossed loosely.

“You know,” she said, her voice rough with sleep, “most people knock before sending haunted shadows into a woman’s bedroom.”

Acheron did not move.

The silver in his eyes reflected faintly in the dark.

“I did not wake you.”

Eva looked pointedly toward the shadow currently attempting to disappear behind his boots.

The shadow froze.

Interesting.

Very interesting.

“You’re going to sit there and pretend your evil smoke creature wasn’t crawling under my door?”

The shadows around him shifted sharply.

Almost defensive.

Acheron’s expression remained perfectly controlled.

“It was observing.”

“That sentence somehow made the situation worse.”

Silence settled between them.

The corridor felt colder tonight.

Or maybe that was just him.

Eva studied him more carefully now.

He still wore black from throat to boots, though without the heavy ceremonial coat from dinner earlier. The dark fabric beneath it looked simpler somehow, softer at the edges. His silver hair looked slightly disordered too, as though he had been running restless hands through it.

That felt strangely human.

The realization unsettled her immediately.

Gods were easier to survive when they felt less real.

“You’re awake late,” she said eventually.

“So are you.”

“Yes, but I’m emotionally unstable and trapped in the land of the dead. What’s your excuse?”

One corner of his mouth twitched faintly.

There.

Again.

That almost-expression.

Eva noticed immediately.

“You nearly smiled.”

“I did not.”

“You absolutely did.”

Acheron looked genuinely offended by the accusation.

That, unfortunately, made it worse.

Eva bit back a laugh.

The shadows around him stirred restlessly again, slipping slowly across the corridor floor toward her bare feet.

They stopped just short of touching her.

Like nervous animals.

Eva stared downward.

“…Your darkness appears to have attachment issues.”

“They are part of me.”

“That is significantly more concerning than comforting.”

Acheron’s gaze lowered briefly toward the floor.

The shadows immediately retreated.

Interesting.

They obeyed him.

Mostly.

The silence stretched again.

Not awkward exactly.

Just strange.

Eva realized suddenly that this might be the first moment since arriving in the Underworld where Acheron did not look entirely composed.

Not weak.

Never weak.

But distracted.

His attention kept drifting toward her and then sharply away again, as though he disliked the instinct itself.

Like looking too long created problems.

Which, admittedly, seemed accurate.

“You’ve been standing outside my room,” Eva said slowly, “for how long exactly?”

A pause.

Too long of a pause.

“…Acheron.”

“I was ensuring the contract remained stable.”

Eva blinked.

“That is the most suspicious explanation I’ve ever heard.”

“The fracture between realms remains volatile.”

“So naturally you decided the best solution was lurking in hallways at midnight?”

His silver eyes narrowed slightly.

“I do not lurk.”

“You are literally standing in darkness outside my bedroom while your shadows spy on me.”

Another pause.

“…Fair point.”

Eva stared.

The God of Death had just admitted she was right.

Somewhere in the palace, reality itself probably cracked slightly from shock.

A faint wind moved through the corridor then, carrying the distant sound of screaming souls from the river below. Eva wrapped her arms tighter around herself automatically.

Acheron noticed.

The temperature around them shifted instantly.

Warmer.

Not warm, exactly.

But less painfully cold.

Eva frowned.

“You did that on purpose.”

His expression hardened immediately.

“No.”

“You absolutely did.”

“I adjusted the surrounding atmosphere to maintain structural balance within the corridor.”

Eva stared at him flatly.

“That was the least convincing sentence anyone has ever spoken to me.”

The shadows near his feet twisted sharply again.

Annoyed shadows now.

Remarkable.

Acheron stepped closer before she fully realized he had moved.

Not threateningly.

Just suddenly.

One moment he stood several feet away.

The next he stood close enough that she could see faint silver fractures beneath the pale skin near his throat.

Eva’s pulse stumbled.

Unfortunately, her body appeared to be developing deeply inappropriate reactions to proximity-based danger.

Acheron’s gaze fixed briefly on her face.

Then lower.

Toward the pulse in her throat.

The air between them shifted.

Heavy.

Still.

Eva became painfully aware that she was barefoot, half-asleep, and wearing a thin borrowed nightshirt while standing alone in a dark corridor with the God of Death.

Excellent decision-making, truly.

Acheron’s shadows crept slowly toward her again.

This time, one brushed lightly against her ankle.

Heat surged violently through the corridor.

Acheron went completely still.

The shadows recoiled instantly.

And beneath the silence—

That heartbeat returned.

Once.

Hard enough that Eva felt it more than heard it.

Acheron’s jaw tightened immediately.

The silver in his eyes darkened.

Not cold now.

Hungry.

Eva’s breath caught slightly.

Neither of them moved.

The heartbeat came again.

Closer this time.

Almost painful.

And suddenly Eva understood something terrifying.

The God of Death was not standing outside her room because he feared the contract.

He was standing there because something inside him kept pulling him back.
