The first thing Luna felt… was pain.

Not the sharp, fleeting kind.

No—this was deep. Burning. Suffocating pain that spread through her body like she had been crushed and stitched back together wrong.

Her breath came in shallow gasps.

“…I’m alive?”

The last thing she remembered was the blinding white lights of a hospital ceiling… the rhythmic beeping of machines… and then silence.

She had died.

That much she knew.

So why—

A sudden rustling sound snapped her thoughts apart.

Luna’s eyes shot open.

Green.

Everywhere was green.

Tall, towering trees stretched endlessly toward the sky, their thick roots twisting across the ground like ancient serpents. The air was humid, filled with the scent of earth and wild plants.

And the sounds—

Low growls echoed in the distance.

Something primal. Dangerous.

Her heartbeat spiked.

“This… isn’t a hospital.”

She pushed herself up—

—and froze.

Her hands were smaller.

Softer.

Delicate.

“…What?”

Her fingers trembled as she brought them closer to her face.

Pale skin. Slender wrists.

Not hers.

Not her old body.

A cold realization crept up her spine.

“I… transmigrated?”

Before she could process further—

CRACK.

A branch snapped nearby.

Her head whipped toward the sound.

From the shadows between the trees… something moved.

A figure.

Tall.

Broad.

And unmistakably inhuman.

Golden eyes gleamed in the darkness.

Locked onto her.

Luna’s breath caught.

“…No way.”

The man stepped forward slowly.

Muscles coiled under sun-kissed skin, his frame powerful, predatory. His hair was dark, slightly wild, and his presence—

Oppressive.

Behind him—

A flicker.

A tail.

A wolf’s tail.

Her mind went blank.

Beastman.

Her instincts screamed.

Run.

But her body—

Wouldn’t move.

His gaze dragged over her, sharp and assessing… before narrowing slightly.

“…A rabbit.”

His voice was low. Rough.

Dangerous.

Luna felt her throat tighten.

Of all things—

She had become prey.

⚠️ System Awakening

Suddenly—

A sharp pain exploded in her head.

“Ah—!”

She clutched her skull as a cold, mechanical voice echoed in her mind.

[System Initializing…]

[Host detected: Luna Vale]

[Race Identified: Rabbit Beast – Lowest Tier]

[Condition: Critical]

“What—?”

[Activating: Divine Medical & Fertility System]

A soft chime followed.

Then—

A translucent blue screen appeared before her eyes.

Luna stared at the panel.

“…A system?”

Her heart pounded—not with fear this time, but something else.

Hope.

But before she could explore it—

The wolf beastman took another step closer.

“Why are you alone?” he asked, voice colder now. “Where is your tribe?”

Luna swallowed.

Think.

Think!

“I…” Her voice trembled. “I don’t have one.”

Silence.

His gaze sharpened.

“…A stray.”

Not pity.

Not concern.

Assessment.

Like he was deciding whether she was worth anything at all.

Luna’s nails dug into her palm.

If she didn’t act—

She would die here.

🐺 The Predator’s Judgment

The wolf crouched slightly, lowering himself to her level.

Still towering over her.

Still overwhelming.

“You’re injured,” he said flatly.

Luna blinked.

Only then did she realize—

Her body was covered in bruises.

Blood stained her arm.

Her HP…

12 out of 50.

She was barely alive.

“I can fix it,” she said suddenly.

The words slipped out before she could stop them.

The wolf’s brow furrowed.

“…You?”

A rabbit.

Weakest of the weak.

Claiming she could heal.

Suspicion flashed in his golden eyes.

Luna inhaled sharply.

Now or never.

“I can heal you too.”

Silence.

Then—

A low, dangerous chuckle.

“…You think I need healing?”

His aura flared.

Oppressive. Crushing.

But—

Luna saw it.

Hidden beneath his strength—

A deep wound along his side.

Dark.

Infected.

Rotting slowly.

Her eyes narrowed.

“You’re dying.”

The words fell softly.

But they hit.

Hard.

The wolf’s expression froze.

For a split second—

His killing intent surged.

Then—

It disappeared.

“…Say that again.”

Luna steadied herself.

Her voice didn’t shake this time.

“That wound… it’s poisoned. You’ve been suppressing it, but it’s spreading.”

A pause.

A long, heavy pause.

Then—

“…Fix it.”

🌿 First Use of the System

[Healing Skill Activated]

[Target: Wolf Beastman – Unknown Identity]

[Energy Cost: 5]

Luna raised her trembling hand.

A faint green glow gathered at her fingertips.

Warm.

Gentle.

Alive.

Even she felt it—

The power flowing through her.

She placed her hand lightly against his side.

The moment she did—

His body tensed.

“Don’t move,” she whispered.

For some reason—

He didn’t.

The light spread slowly.

Seeping into the wound.

Purifying.

Restoring.

The dark, corrupted flesh began to fade.

The wolf’s breathing hitched.

“…What is this…”

[Healing Successful]

[Energy Remaining: 3/30]

Luna pulled her hand back.

Her vision blurred slightly from exhaustion.

But—

The wound was gone.

Completely.

The forest fell silent.

The wolf stared at his side.

Then at her.

Something had changed in his gaze.

No longer just assessing.

But—

Focused.

Sharp.

“You…”

He stepped closer.

Too close.

Luna’s back hit the tree behind her.

Her heart slammed against her ribs.

“…What are you?”

She held his gaze.

“I’m the one who saved you.”

A dangerous answer.

But a necessary one.

For a moment—

Neither moved.

Then—

Unexpectedly—

He smirked.

“…You’re interesting.”

A new panel appeared.

Slight trust established

Luna’s eyes widened.

“…Bond system?”

So this world—

Wasn’t just about survival.

It was about connection.

And power through it.

🐺 A Dangerous Offer

The wolf straightened, his presence still overwhelming—but different now.

Less hostile.

More… controlled.

“You don’t have a tribe,” he said.

It wasn’t a question.

Luna shook her head.

“…No.”

Another pause.

Then—

“Come with me.”

Her breath caught.

“What?”

“You’ll die alone,” he said bluntly. “You’re too weak.”

True.

Painfully true.

“But with me…”

His golden eyes locked onto hers.

“You might survive.”

Might.

Not will.

He wasn’t offering safety.

He was offering a chance.

Luna hesitated.

Every instinct screamed danger.

But—

What choice did she have?

She glanced at her system panel.

Low HP.

Low energy.

No protection.

If she stayed—

She would die.

Slowly.

Alone.

She exhaled softly.

“…Fine.”

A faint glint of approval crossed his eyes.

“Good.”

He turned without another word.

“Keep up.”

And just like that—

He started walking.

Luna stared at his back for a second.

Then—

She pushed herself forward.

Step by step.

Into the unknown.

[Quest Unlocked]

Reward:

System Upgrade

New Ability Unlock

Luna glanced at the glowing panel one last time.

Then at the man ahead of her.

Kai Thorn.

She didn’t know his name yet.

But she would.

And somehow—

She knew this was only the beginning.

From prey…

To something far more dangerous.

The forest grew darker the deeper they went.

Luna struggled to keep up.

Her legs ached, breath uneven, every step heavier than the last. The earlier healing had drained her, and her body—this fragile rabbit body—was nowhere near built for endurance.

Ahead of her, Kai didn’t slow down.

Not once.

Not even when her steps began to falter.

Cold.

Unforgiving.

Exactly what she expected from a predator.

“Wait…” she finally whispered.

He stopped.

Not because he cared—

But because she had spoken.

Slowly, he turned his head.

Golden eyes flicked over her.

Sweat clung to her skin. Her breathing was shallow. Weak.

“…You’re already slowing down?”

There was no mockery in his tone.

Just observation.

Luna clenched her fists.

“I’m not used to… this body yet.”

A lie—and not.

He studied her for a moment.

Then—

He turned fully.

Walked back toward her.

Luna stiffened.

Every instinct screamed at her to step back—but she held her ground.

Kai stopped right in front of her.

Too close again.

Always too close.

“…You won’t survive like this,” he said.

“I know.”

No excuses.

No denial.

That answer seemed to interest him.

For a moment, silence lingered between them.

Then—

Without warning—

He crouched.

“…Get on.”

Luna blinked.

“What?”

His gaze hardened slightly.

“I’m not repeating myself.”

Her heart skipped.

A wolf… offering to carry her?

This wasn’t kindness.

It was practicality.

But still—

“I can walk—”

“You’ll collapse before we reach the territory.”

His voice dropped slightly.

Lower.

More dangerous.

“…And I don’t carry dead weight.”

Luna hesitated.

Then slowly—

Carefully—

She climbed onto his back.

The moment her arms wrapped around him—

His body went still.

For a second.

Just a second.

Then—

He stood.

Effortlessly.

And started walking again.

🔥 Close Proximity

Luna’s breath hitched.

His body was… warm.

Solid.

Every step steady, controlled.

His scent—

Wild.

Earthy.

Dangerous.

Her fingers tightened slightly against his shoulder.

She could feel the tension in his muscles.

The awareness.

He wasn’t unaffected.

“…Don’t hold too tight,” he said suddenly.

Her cheeks flushed.

“I’m not—”

“You are.”

Silence.

Then—

“…You’re shaking.”

That made her freeze.

“I’m not scared,” she muttered.

A pause.

“…Good.”

But his tone said otherwise.

🐺 Wolf Territory

By the time they arrived—

The sun was already setting.

And what Luna saw—

Made her breath catch.

A massive clearing stretched ahead.

Stone dens carved into a cliffside.

Fires burning.

Dozens of figures moving—

Men.

All men.

All powerful.

All—

Beastmen.

Wolves.

The moment Kai stepped into the territory—

Everything changed.

Conversations stopped.

Heads turned.

Eyes—

Locked onto her.

A rabbit.

On their alpha’s back.

The air grew tense.

Heavy.

Dangerous.

Kai didn’t stop walking.

Didn’t explain.

Didn’t acknowledge anyone.

He simply carried her straight through the center of the camp.

Dominance.

Absolute.

“Alpha’s back…”

“A rabbit?”

“What is that thing doing here—”

Whispers spread like wildfire.

Luna felt every gaze.

Every ounce of hostility.

Her grip tightened unconsciously.

Kai noticed.

“…Ignore them.”

Simple.

Direct.

But—

Reassuring.

In his own way.

🐾 Challenge

Just as they reached the largest stone den—

A figure stepped forward.

Tall.

Scarred.

Eyes sharp with challenge.

“…Kai.”

The name.

So that was his name.

Luna repeated it silently.

Kai Thorn.

The man didn’t look at Luna.

Only at Kai.

“You brought prey into the territory?”

His voice carried authority.

Not equal—

But close.

Kai stopped.

Slowly.

“…Move.”

A warning.

The man didn’t.

“This weak thing will attract trouble,” he said. “Or worse—become useless.”

Luna’s jaw tightened.

Kai’s expression didn’t change.

But the air—

Shifted.

Dangerously.

“She’s under my protection.”

Silence.

The words hit harder than a threat.

The entire clearing stilled.

The man’s eyes flicked to Luna for the first time.

Cold.

Evaluating.

“…Why?”

Kai didn’t answer immediately.

Instead—

He stepped forward.

Closing the distance.

Forcing the man back a single step.

“She’s useful.”

That was all.

But it was enough.

After a long moment—

The man exhaled sharply.

“…Fine.”

He stepped aside.

“But if she causes problems—”

“She won’t.”

Final.

Absolute.

The matter ended there.

🌿 Private Space

Kai carried her inside his den.

Dark.

Quiet.

Isolated.

He finally crouched—

Allowing her to slide off his back.

The moment she did—

Her legs nearly gave out.

He caught her wrist.

Firm.

Steady.

“…Pathetic.”

But—

He didn’t let go immediately.

Luna steadied herself.

“…I’ll get stronger.”

A promise.

More to herself than him.

His gaze lingered on her.

Then—

Slowly—

He released her.

“…You better.”

Luna’s eyes lit up.

“This… changes everything.”

🔥 Night Tension

Later that night—

The den was silent.

One fire.

Two people.

Too close.

Kai sat across from her.

Watching.

Always watching.

“You’re not normal,” he said suddenly.

Luna met his gaze.

“…Neither are you.”

A beat.

Then—

A faint smirk.

“…Fair.”

Silence returned.

But it wasn’t empty.

It was—

Heavy.

Charged.

“Why help me?” he asked.

Direct.

Luna didn’t look away.

“Because you needed it.”

“And?”

“…Because I need you too.”

That—

Caught him off guard.

Just slightly.

His eyes narrowed.

“…Careful.”

His voice dropped.

Lower.

“You don’t understand what that means.”

Luna’s heart pounded.

But she didn’t back down.

“…Then teach me.”

🔗 Bond Increase

[Bond Level Increased: 2 → 3]

[Effect: Increased Trust + Emotional Awareness]

Kai looked at her—

Longer this time.

Deeper.

Something had shifted.

Again.

“…Sleep,” he said finally.

But his tone was different.

Less cold.

More—

Controlled.

The wolf territory did not sleep.

Even in the dead of night, Luna could feel it—

the constant presence of predators.

Breathing. Moving. Watching.

She sat near the dim fire inside Kai’s den, unable to fully relax.

Every sound made her tense.

Every shadow felt alive.

And Kai—

He hadn’t slept.

Not once.

Leaning against the stone wall, arms crossed, golden eyes half-lidded—

But alert.

Always alert.

“You should rest,” Luna said quietly.

He didn’t move.

“…I am.”

She almost smiled.

Almost.

🌑 Something Else Is Watching

A sudden shift in the air made her freeze.

Not danger—

Something sharper.

Colder.

Her instincts flared.

Not like Kai’s overwhelming dominance.

This was…

Silent.

Hidden.

Her eyes flicked toward the entrance of the den.

“…Kai.”

His gaze snapped to her instantly.

“What.”

“There’s someone outside.”

Silence.

Then—

A faint chuckle echoed from the darkness.

Low.

Smooth.

Amused.

“Well… that’s interesting.”

Luna’s breath hitched.

A figure stepped into the faint firelight.

Tall.

Lean.

Graceful.

Dark hair fell across sharp eyes that gleamed with quiet danger.

Unlike Kai—

This man didn’t feel like a storm.

He felt like a blade in the dark.

Precise.

Deadly.

Watching.

🐆 Nyx Appears

Kai’s expression hardened instantly.

“…Nyx.”

So this was him.

Nyx Shade.

The air shifted.

Tension—thick, sharp, immediate.

Nyx’s gaze slid to Luna.

Slowly.

Deliberately.

“…This is what you brought back?”

His voice was soft.

Too soft.

Luna felt it—

The weight of his attention.

Not dismissive.

Not mocking.

Curious.

Dangerously curious.

Kai stepped forward slightly.

Just enough to block her from view.

“Leave.”

Nyx tilted his head.

“…You don’t usually hide things from me.”

“I’m not hiding her.”

“You’re standing in front of her.”

A pause.

Then—

A faint smile curved Nyx’s lips.

“…That’s new.”

🔥 First Jealousy Spark

Luna frowned slightly.

She wasn’t stupid.

This—

This dynamic—

It wasn’t just tension.

It was something deeper.

Something personal.

Nyx took another step forward.

Unbothered by Kai’s presence.

Unafraid.

“I heard rumors,” he said lightly. “But I didn’t expect this.”

His gaze locked onto Luna again.

Sharp.

Focused.

“…A rabbit.”

Luna straightened.

“I have a name.”

That—

Caught his interest.

“Oh?”

Kai’s eyes flicked toward her briefly.

Surprised.

Nyx smiled faintly.

“…Then say it.”

“Luna.”

The name lingered in the air.

Nyx repeated it softly.

“…Luna.”

Something about the way he said it—

Made her chest tighten.

🔗 System Reaction

[New High-Tier Target Detected]

[Bond System Activating…]

💞 Bond Status

Target: Nyx Shade

Bond Level: 1 (Curiosity)

Luna’s eyes widened slightly.

So fast?

This system…

It reacted to connection.

Interest.

Attention.

And Nyx—

He was very interested.

🐺 Kai’s Reaction

Kai stepped forward again.

This time—

More forcefully.

“That’s enough.”

His voice dropped.

Low.

Dangerous.

Nyx didn’t move.

Didn’t back down.

Instead—

He leaned slightly to the side.

Just enough to see Luna again.

“…You’re guarding her too tightly.”

Kai’s jaw clenched.

“She’s under my protection.”

Nyx’s eyes flickered.

Once.

Then—

He smirked.

“…Since when do you claim things so quickly?”

Silence.

Heavy.

Sharp.

Kai didn’t answer.

And that—

Said everything.

😏 Nyx Moves Closer

Before Luna could react—

Nyx stepped past Kai.

Fast.

Silent.

He was suddenly right in front of her.

Too close.

Always too close.

But different from Kai.

Kai was overwhelming.

Nyx was…

Invading.

Her space.

Her awareness.

Her breath.

“…You don’t smell like prey,” he murmured.

Luna froze.

“What?”

His eyes narrowed slightly.

“Not fear.”

A pause.

“…Something else.”

Luna’s heart pounded.

The system.

It had changed her.

Even subtly.

And Nyx—

He noticed.

🔥 Jealousy Ignites

Kai moved.

Fast.

His hand grabbed Nyx’s shoulder—

Pulling him back.

Hard.

“Don’t touch her.”

Nyx glanced at him.

Unbothered.

“…I didn’t.”

“But you were about to.”

Their gazes locked.

And for the first time—

Luna felt it clearly.

Jealousy.

Raw.

Unspoken.

Dangerous.

🧩 System Alert

[Jealousy Trigger Detected]

[Bond Growth Opportunity Increased]

Luna blinked.

“…What?”

So—

Conflict between mates…

Actually helped her?

This system—

Was dangerous.

🌿 Luna Intervenes

“Stop.”

Her voice wasn’t loud.

But it cut through the tension.

Both of them looked at her.

That alone—

Was shocking.

Two predators.

Listening.

Luna exhaled slowly.

“I’m not something to fight over.”

Nyx’s lips twitched.

“…Aren’t you?”

Kai didn’t speak.

But his gaze—

Intense.

Focused.

Said otherwise.

🌑 Nyx’s Decision

After a long pause—

Nyx stepped back.

Relaxed again.

Like the tension had never existed.

“…Interesting.”

He turned toward the exit.

“But this isn’t over.”

His eyes flicked back to Luna.

“…Luna.”

A promise.

A warning.

Something in between.

Then—

He disappeared into the darkness.

Silent as he came.

🔥 Aftermath

The den fell quiet again.

But the air—

Still heavy.

Kai didn’t move immediately.

Then—

“…Stay away from him.”

His voice was sharper now.

More controlled.

More—

Personal.

Luna frowned.

“Why?”

A mistake.

His gaze snapped to hers.

“…He’s dangerous.”

“So are you.”

Silence.

A long one.

Then—

“…Not to you.”

The words were quiet.

But they hit harder than anything else.
