Harem Startup : The Demon Billionaire is on Vacation

Chapter 419 – I am Behaving

Because the Avariels couldn’t know. Not about him. Not about Sira. Not what they were. Not what they did. He was a charming, if eccentric, businessman. She was a prideful heiress with old money and sharper teeth than most socialites.

That was all.

No horns. No hell.

Just a misunderstood CEO and his very aggressive girlfriend who occasionally thirsted for war.

Ariel sniffed softly and pulled her blouse back on.

Her mother hugged her again. This time, Ariel returned it fully. Arms around her mother. Head pressed against her shoulder.

Lux looked away. Not out of modesty. Just because the ache in his chest was sharp enough to count as debt.

Rava checked her phone. ”My assistant is arriving in five.”

The mother nodded. Her face was still blotchy, but her steps were steadier now.

The father extended his hand to Lux.

Lux took it.

”We owe you more than we can repay,” the man said quietly. ” I will send the invitation.”

”Thank you. Just take care of her,” Lux said.

The handshake lingered. Then broke.

A moment later, the Avariels and Rava were walking down the hall. Ariel turned to look back. Once. Just once.

Lux raised a hand. Just a small wave.

She smiled.

Then she was gone.

Silence.

Pearls still dotted the floor. Like emotional landmines. Like wealth that felt too heavy to touch.

Sira leaned back in her seat and exhaled. ”So,” she said, ”do I get to kill someone now or not?”

Lux pinched the bridge of his nose.

”We’re not killing the Delmars.”

”Yet.”

”At all.”

Sira rolled her eyes. ”You’re no fun.”

”I’m a CFO,” he deadpanned. ”We don’t do fun. We do quarterly reports and internal audits.”

Sira smirked. She probably caught the tail end of that.

”Well,” she said, stretching, ”now that we’ve reunited long-lost families, exposed a scandal, and made me sit through feelings, can we go back to doing something spicy? Like blackmail? Or afternoon tea with cursed pastries?”

Lux stood. Adjusted his jacket. Brushed a pearl off the chair.

”Let’s go home first,” he said.

”Ooooh. Planning. That’s foreplay for you, isn’t it?”

He didn’t answer.

But his smirk said everything.

Soon, they were back in the car.

Lux’s hand rested lightly on the leather steering wheel, wrist loose, fingers flicking the turn signal out of sheer formality—he didn’t need to signal. Mortals cleared the lane the second his aura brushed them. But hey. Civility. Urban decorum. He was trying.

Outside the windows, the city blurred past in long streaks of gold. Shopfronts gleamed. A gentle haze of afternoon smog made everything look like it had been brushed with a wet dream filter.

And Sira?

Sira had her legs sprawled across his lap, one heel discarded, the other foot hanging out the window like she owned the air.

”Eyes on the road, darling,” she murmured lazily, tapping her toes against his thigh.

”I am,” Lux said smoothly, even as her calf shifted... higher.

Men on the sidewalks openly stared. Construction workers. Delivery drivers. Bankers. Their eyes dragged over Sira like she was an art piece wrapped in danger. Women weren’t any better—snapping photos of Lux from behind sunglasses, holding their breaths like catching his gaze would bankrupt them.

Most didn’t even realize why they were staring. Just that something about the couple in the car was wrong. Too perfect. Too surreal. Predatory beauty at rest.

A few lifted their phones.

[Threat assessment: negligible. Civilians attempting documentation. Recommending passive glamor veil.]

’Let them look.’

[Understood. Logging minor ego inflation: +0.02 Charisma.]

Sira’s grin widened.

”You know,” she said, lips curling like a sin, ”we could have sex right now.”

Lux didn’t even blink. ”No.”

”Ohhh come on,” she purred. ”The windows are open. The mortals are already staring. Let’s give them something to really gawk at.”

He gave her a side glance. ”Sira. Behave.”

”I am behaving,” she said, dragging her foot—her bare foot—across the seam of his pants. ”This is me being good.”

His fingers twitched on the wheel. ”You can wait.”

”But why wait when I could just...” Her toes pressed against him. Right there. Through fabric.

Lux inhaled sharply. ”Sira.”

”I know,” she said innocently. ”You’re driving. But you’re not a mortal, are you? I mean, surely an ancient hellborn prince can multitask. Ride and drive, right?”

His jaw clenched. ”I’m trying not to crash my new car.”

She gave a soft hum. ”Mortal realm has made you soft.”

”I’m just trying to respect basic traffic laws.”

”And I’m trying to respect your d*ck,” she whispered with mock reverence, her foot pressing harder, making him shift in his seat.

And then—

An explosion.

Not sound first. Pressure. A sudden, collapsing nothingness that punched through the air like a giant’s fist. The windows rippled. A deep hum followed, like the echo of something ancient waking up beneath the city.

Then came the heat.

A fireball erupted just two blocks ahead—concrete split, light poles snapped, and the street turned into a fountain of shattered glass and screaming metal. The shockwave hit a moment later.

BOOOOOM—

Lux jerked the wheel. Tires screeched. Sira yelped—not from fear, but excitement. The car fishtailed hard, then corrected, drifting cleanly into the adjacent lane.

Behind them, two more blasts struck—closer, sharper. One kissed the rear bumper.

”FCK!” Lux hissed. ”I just bought this thing!”

Smoke curled around them.

[Emergency Alert: Proximity Hostile Signature Detected.]

[Classification: Demonic. High-tier. Origin: Infernal Realm.]

[Advisory: Deploying inner defensive shell—wait. No enchantments detected on vehicle.]

’Yeah. It’s mortal. I wanted something normal.’

[...Why, sir?]

’Because I’m allowed to have nice things that don’t glow in twelve languages.’

The sky cracked.

A dome—black and red, pulsing with ancient Infernal sigils—slammed down around them. The street went dim. Buildings beyond blurred like a painting in water. The dome was tall, circular, wide enough to trap four city blocks, and burning from the inside with oily mana.

Trapped.

The car skidded to a stop. Smoke hissed from the tires. Lux threw it into park.
