Harem Startup : The Demon Billionaire is on Vacation

Chapter 817 – Primordial Sin Effects [Part 1]

The weekend came.

And with it... absolute, unapologetic chaos.

Lux’s chamber looked like a battlefield.

Not the clean, tactical kind with formations and strategy.

No, this was the kind of battlefield where dignity went to die.

Silk sheets tangled like they had personally lost a war. Pillows thrown across the room like casualties. Clothing. No, not clothing, remnants of clothing scattered everywhere. Bras hanging off the chandelier like some kind of artistic statement. Panties draped over the edge of a chair that definitely did not consent to being involved in whatever happened last night.

And then there were the... tools.

Whips. Ribbons. Restraints.

A single heel, standing proudly on the table like it survived the apocalypse.

Lux blinked slowly.

”...Yeah,” he muttered under his breath, voice rough but calm. ”Friday.”

Friday is Orgy night.

His body shifted as he sat up, the sheets sliding down his torso, revealing a canvas of marks, faint bites, scratches, bruises blooming like soft constellations across his skin. None of them hurt. Not really. If anything, they felt... warm.

Alive.

He rolled his shoulders once, testing.

No stiffness.

No exhaustion.

If anything...

He felt better.

Stronger.

”...Huh.”

That part still caught him off guard.

Because logically?

This should’ve destroyed him.

Physically. Mentally. Spiritually.

Instead, Lux swung his legs off the bed, posture steady, movements controlled, not sluggish, not heavy. Just... normal.

No.

Better than normal.

He exhaled slowly, fingers brushing through his hair before he leaned forward, elbows resting on his knees.

”System,” he muttered. ”Status.”

A pause.

[Displaying current status, sir.]

[Name: Lux Vaelthorn]

[Class: Sovereign of Twin Sins]

[Level: 400]

[HP: 3,600,000]

[DP: 1,400,000]

[Charisma: 999 (MAX)]

[Magic Affinity: 1,650]

[Strength: 1,350]

[Agility: 1,450]

He stared at it for a second.

Then slowly... clenched his hands.

The feeling came instantly.

That heat.

Not just physical.

Something deeper.

Something coiled under his skin, pulsing, not wild, not unstable. Controlled. Responsive. Like a beast that had finally decided to stop fighting the leash... because it realized it was the leash.

Lux’s lips curled.

”...Yeah.”

There it was.

That quiet, dangerous satisfaction.

Not loud. Not dramatic.

Just... certainty.

He flexed his fingers again, feeling the subtle shift of energy responding to his will.

And the weirdest part?

It didn’t feel foreign anymore.

It felt natural.

Like it had always been there.

He just stopped pretending otherwise.

”I’m getting used to this,” he murmured.

That alone should’ve concerned him.

It didn’t.

That was probably more concerning.

His gaze drifted.

Across the room.

Naomi, curled on her side, blanket barely covering her, hair messy, breathing slow and even. Mira sprawled like she owned the entire bed, because she probably did. Ely half tangled in the sheets, one arm stretched out like she passed out mid-thought. Rava... somewhere under a pile of blankets that definitely wasn’t just blankets.

Sira leaned against the headboard, still asleep somehow, posture almost regal even like that. Lullaby... well, Lullaby was just Lullaby, completely gone, wrapped in her own little world.

Lux watched them.

Quietly.

There was no rush.

No tension.

Just... stillness.

And something softer.

They weren’t exhausted.

That was the part that kept catching his attention.

They looked...

Satisfied.

At ease.

Not drained.

Not broken.

If anything...

Stronger.

He exhaled through his nose.

”...Yeah. That tracks.”

His eyes narrowed slightly, thoughtful.

Because that explained a lot.

Mira.

He remembered that.

Three movements.

Three.

Her grandfather and she handled it like it was a warm-up.

At the time, he brushed it off.

Now?

”Right.”

He leaned back slightly, running a hand over his face.

”I guess elixirs are useless for now.”

He stood up slowly.

Careful.

Not because he was tired.

But because stepping on a whip first thing in the morning felt like a bad life decision.

He navigated the room like a veteran, avoiding... everything.

”Hazard zone,” he muttered under his breath.

His foot nudged something.

He glanced down.

”...Is that mine?”

A pause.

”...Nope.”

He kept walking.

Bathroom.

Shower.

Steam filled the space quickly, warm water cascading over his skin, washing away the faint traces of last night while not quite erasing it.

Because the marks remained.

The memory lingered.

The feeling?

Yeah.

That didn’t go anywhere.

Lux leaned his head back slightly, letting the water hit his face.

And then... He started whistling.

Soft.

Casual.

Like a man who absolutely did not just survive a Friday night that could legally be classified as an event.

[Sir, do you want to check Hell’s financial reports?]

The voice came in, flat.

Professional.

Judging.

Lux didn’t even open his eyes.

”No.”

A pause.

[You do not want to check it?]

”No.”

Another pause.

Longer this time.

[It does not like you, sir.]

Lux snorted. ”I’ve been told worse.”

[Are you sick?]

He cracked one eye open slightly.

”...Excuse me?”

[Your behavioral pattern indicates deviation from standard operational efficiency. You have ignored financial oversight. This is concerning.]

Lux let out a quiet breath, shaking his head slightly.

”Relax.”

[That is not within my operational parameters, sir.]

”Yeah, I noticed.”

He ran a hand through his wet hair, pushing it back.

”I will give you permission for a full scan.”

[Confirmed.]

A brief silence.

[Scanning.]

Lux leaned against the wall, arms relaxed at his sides, eyes half-lidded.

Water continued to run.

Steam thickened.

Seconds passed.

[Scan complete.]

A pause.

[No abnormalities detected.]

Lux’s lips curved.

”See?”

[This is illogical.]

”That I’m fine?”

[That you are not concerned.]

He chuckled under his breath.

”Maybe I’m evolving.”

[That is not reassuring.]

”Not for you.”

[What is the cause of this behavioral shift, sir?]

Lux tilted his head slightly, considering.

Water dripped down his jaw.

”...Dunno.”

He exhaled.

Slow.

Measured.

”...Maybe...”

His eyes lowered slightly.

”...Because I stopped resisting it.”

A beat.

”...Or maybe...”

His fingers flexed again.

That same heat.

That same control.

”It’s the blessing.”

[Clarify.]

Lux smirked faintly.

”Primordial Lust.”

Silence.

A long one.

The kind that usually meant the system was processing something it didn’t like.

[That is a concerning variable.]

”Yeah.”

[Your mental state may be affected.]

”Probably.”

[Your judgment...]

”Still better than most.”

A pause.

[That is statistically accurate.]
