Harem Startup : The Demon Billionaire is on Vacation

She said nothing.

"And the stronger the demon? The worse the instinct."

He walked slowly, explaining like he was reciting something burned into him.

"Sin Lords. Royal demons. The great bloodlines—they bear the mark. The moment they birth more than a handful of heirs, the realm begins to suffer. Balance shifts. The sin tugs harder. Factions fracture. We turn on each other. We consume each other."

Lux met her gaze, serious now.

"Our instinct isn't to lead. It's to dominate. To kill. To take."

He paused.

"Even from each other."

Mira's breath hitched.

"So… your parents had one heir. You."

He nodded. "They called it safe. A balancing act. The power was there, but contained. Barely."

"…And they just left you to deal with it."

"Yup," he said. "Congratulations, Vaelthorn. You're the first dual-sin anomaly. Fix the economy, unify Hell, don't die."

He smiled—but it didn't reach his eyes.

Mira whispered, "Gods…"

He shrugged again. "I survived."

"You shouldn't have."

"Story of my life."

She was quiet a moment longer, then said, "That's why you built this place."

Lux nodded. "My mansion. My rules. My people. My system. I needed something I could control. Something I could grow. A team, a family… not a kingdom. A home."

Mira swallowed thickly. "And the orphanages?"

His voice softened. "It's not about guilt. It's not about branding. I just… wanted to give someone the thing I never had."

She didn't say anything.

She just sat there. Silent. Watching him with new eyes.

Not just the sharp CFO. Not just the dangerous incubus.

But him.

Lux. Greed and Lust. The unwanted miracle who chose to build instead of break.

She exhaled. "You really don't make it easy to hate you."

"I try," he said, offering her a grin again—smaller now. "But I'm cursed with good PR."

She smirked despite herself.

And for a moment?

Neither of them said anything.

Because maybe—just maybe—this was what truth looked like.

Ugly. Strange. Tender.

And…

Worth staying for.

Mira sat there, legs crossed on the gym bench like she wasn't about to drop a life-altering declaration. The robe had slipped slightly from her shoulder, revealing skin kissed by morning chill and pride. Her eyes flickered—not soft, not smitten, but decided.

She looked at him with all the grace of someone closing a business merger.

"Anyway," she said, brushing imaginary dust from her thigh, "I like you."

Lux blinked.

She continued, voice breezy. "And I guess I'll join your harem then."

Lux froze.

Wait—what?

Not because he hadn't thought about it. Not because he didn't want her. But because—

"Just like that?" he asked, towel slung over his shoulder, sweat still clinging to his skin.

Mira stood, stretching like a bored cat. "Yeah."

Like she was saying 'yeah, I'll take the premium warranty'.

No blushing. No teasing. No breathy confession.

Just Mira. Logical, slightly smug, dragon pride incarnate—signing on like she was merging her firm into his.

He opened his mouth to say something—anything—but she was already walking past him, hips swaying slightly, robe barely tied, confidence leaking off her like cologne.

"I'll move into the mansion," she added over her shoulder. "I need to prep my luggage. Shouldn't take long. I travel light when I'm emotionally committing to a chaos demon prince."

Lux stood there, shirtless and mildly short-circuited.

Then—

She stopped.

Turned.

And approached.

Close.

Too close.

Close enough that he caught the soft notes of her tea-breath, the wild morning tangle of her hair, the curve of her lip as she scanned him up and down with open, amused hunger.

"As for you," she murmured, fingers brushing the line of his abs, "sweaty man isn't usually my type."

His brow quirked.

"But I like the scene," she said, grinning now. "And I do know what I'm getting. Above the brain. Above the PR. Above the broody silent investor charm…"

She glanced down.

Eyes lingering on his cock.

"Well," she said, clearly not in a rush. "It looks nice."

Lux exhaled through his nose. "Appreciate the review."

She smiled. "Let's see if I can get myself a demon-dragon-greed-lust-sins child out of this."

And before he could even raise an eyebrow—

She leaned in and kissed him.

Hard.

Hot.

Her mouth crashed into his like they were the ones burning down the stock market. No hesitation, no teasing. Just tongue, breath, teeth, heat. She bit his lower lip, then licked it. Lux's hand found her waist, anchoring her. His tongue moved like a negotiation—sharp, exploratory, thorough.

He tasted pride and fire and the promise of long arguments in bed.

And liked it.

Her fingers curled at the nape of his neck, pulling him deeper. Her knee nudged his thigh like she wanted to climb him, stake her claim in real time.

Then—

She pulled away.

Just like that.

Leaving him slightly dazed, lips parted, towel slipping from his shoulder like it had given up on modesty.

Mira stepped back, tying her robe properly again like nothing happened.

"Oh, right," she said casually, heading for the door, "you're trending in the housewives' group chat."

Lux blinked. "…what?"

"Apparently the pool photos? Instant hit."

He groaned softly.

"And the Lamia queen? She went feral when she found out you left the hotel. I heard she scream at her driver. Slapped her assistant. Some say she's coming back for vengeance."

Mira opened the door and paused. Turned her head slightly, eyes glinting with dragon-level possessiveness.

"Get ready tonight."

Lux raised an eyebrow. "For?"

"I want your best performance," she said.

Then, with a grin that was half threat, half flirt, she added:

"I'm hoarding you."

And she was gone.

Just like that.

The door clicked shut.

Lux stood there in his private gym, half-dressed, fully baffled, mildly aroused, and existentially hijacked.

He blinked at the empty space she left behind.

Then rubbed the back of his neck.

"…Did she just do a hostile takeover?"

No one answered.

He glanced at the mirror, saw his own stunned reflection, and sighed.

"Now I'm aroused," he muttered.

He grabbed the towel again, wiping the sweat that no longer had anything to do with working out.

But despite the chaos…

Despite the suddenness…

Despite the dragon now rearranging her wardrobe to move into his house and possibly his eternal fate—

Lux found himself smiling.

Just a little.

Because yeah.

He liked this dragon too.
