Harem Startup : The Demon Billionaire is on Vacation

Chapter 330 – Immortals Have Issues

That threw her off. ”What?”

He looked down into his cup, then back at her. ”Even among demon royalty. Do you know why?”

Mira didn’t answer.

”Because I have two sins,” he said.

She stared. ”You mean Greed and Lust?”

He nodded. ”Most demons only have one. One sin affinity. One domain. That’s the rule. It’s written into our bones. Two sins?” He scoffed. ”They thought it couldn’t be done.”

He stepped past her and grabbed a fresh towel from the rack.

”My mother,” he said, voice steadier now, ”is the princess of Lust. My father is the Lord of Greed. Their union was... symbolic. Political. But everyone said it would be fruitless. Heirless. You can’t mix sin cores. It destabilizes the lineage. Madness. Corruption. Sterility.”

He looked at her. Really looked.

”But then... after five years of destroying beds and hoping, she got pregnant.”

He smiled faintly.

”And I was born.”

Mira’s brows furrowed.

”I’m the first of my kind,” Lux continued. ”A royal demon with two sins. Some called me a failure when I was small. Too volatile. Too much. But my parents?” He shook his head. ”They put everything on me. Everything. Expectations. Legacy. Hope.”

He crossed his arms again.

”They wanted proof. Proof that their union wasn’t a mistake. That I could be something more than either sin. A demon who could count and seduce. Negotiate and destroy. Feed and restrain.”

Mira whispered, ”Did you?”

Lux smiled. ”I did.”

Then he exhaled, wiping his face again. ”But. Here’s the catch. Since I carry both sins, my legacy? It’s hell.”

”What do you mean?”

”I’m not like normal incubi,” he said. ”I don’t just spill seed and boom—heir. No. Hell, even normal royal demons need time to get their own heir. But me? My essence? My dual-core? It’s unstable. Immortals have issues, Mira. Mine just happen to involve... an unholy amount of sex.”

She choked. ”Wait, so—”

”Yeah.” He gave her a tired grin. ”To make a child? I need repetition. Compatibility. Magical harmony. Which means... a lot of fucking. Often. With women who can actually handle me.”

”...Holy shit.”

”Exactly.”

He looked at her. ”And I want them. All of them. As many as I can love. As many as can love me back. I want a dynasty. Not for pride. Not even for hell.”

He paused.

”I want it for me.”

Mira leaned back, stunned. ”You didn’t cover that up at all.”

”Nope.”

She stared at him like he’d grown a second tail.

”You’re insane. But weirdly... honest.”

”I told you,” Lux said, rolling his neck as he reached for his water bottle. ”No sugarcoating. Just contracts and commitment.”

”And orgasms,” Mira added dryly.

He smirked. ”Preferably.”

The gym had quieted.

Lux sipped his water, wiped his face with a towel, then said, quieter now, ”But yeah... I’m an anomaly. Even for demons. Even across the realms.”

Mira tilted her head. ”You keep saying that. Miracle. Anomaly. Legacy. Big words for someone who downs protein shakes and threatens financial stability.”

He chuckled. ”It’s not a brag. It’s just reality.”

She paused. ”You want kids. You want a dynasty. But... have you ever had any?”

His eyes darkened—not sad, but deeper, like someone flipping to a less-read Chapter in their ledger.

He nodded. ”Sort of.”

”Sort of?”

Lux set his bottle down, crossed his arms loosely. Then gave her a soft, crooked smile that had no seduction in it. Just memory.

”Keep this a secret,” he said. ”Sira knows. That’s about it.”

Mira blinked but nodded. ”Okay.”

”I sometimes donate to mortal realm orphanages,” Lux said. ”Nothing public. No foundations. No plaques with my name.”

”...What?”

He shrugged. ”No one knows it’s me. I just... transfer credits. My assistants don’t even know what the funds are for. I make the final call manually.”

She blinked. ”So you just—drop money into their accounts?”

”And sometimes,” he added, almost embarrassed, ”I make a video call. Ten, twenty minutes max. I wear a blazer, put on glasses. Human disguise. Pretend I’m a foreign businessman who just wants to check in. Some philanthropist. I ask how they’re doing. I listen.”

”Wait. You call them?”

”Yeah,” he said. ”Just to see their faces. Hear their voices.”

He looked away. ”Then I go back to work.”

Silence stretched.

Mira stared at him like he’d just admitted he moonlighted as Santa Claus.

”You donate,” she said, slowly.

”Shocking, I know.”

”You donate.”

He smiled faintly. ”I do.”

”But you’re a Greed demon.”

”Yup.”

She narrowed her eyes. ”So... why?”

Lux leaned against the mirrored wall, his expression shifting. More personal now. Less CFO, more... just him.

”Because I know what it’s like,” he said, voice lower. ”To feel abandoned. Forgotten.”

Mira’s throat tightened. She didn’t interrupt.

”I know some of those kids were left behind. Parents dead. Missing. Or just too busy surviving to care. They grow up feeling like numbers. Debts. Unwanted.”

He exhaled slowly.

”I wasn’t left in an orphanage. But my parents?” He gave a short, hollow laugh. ”They threw their duty at me and ran.”

”Wait,” Mira said softly. ”You don’t have siblings?”

Lux shook his head. ”Nope. Just me.”

”They didn’t try again?”

”Yeah.”

”Wait—your parents went on a honeymoon for centuries and never made more kids?”

”Correct.”

She stared. ”You’re telling me... your parents broke reality to make you, then just left?”

He raised his hands like a guilty man. ”Hey, I told you. I’m a miracle. But miracle or not, most royal demon couples only have two or three children. Tops. While common demons breed like stray cats.”

”Why?”

He looked at her.

And something old flickered behind his eyes. Not just memory. Something deeper. Ancestral. Primordial.

”Because of the curse.”

Mira froze. ”Curse?”

Lux’s voice dropped. The gym suddenly felt colder. Like the air was holding its breath.

”It’s a rule written in the bones of the Underworld,” he said. ”A law older than kings. Older than the Sins themselves.”

He stepped closer, towel in hand, voice quiet but sharp.

”Demons—real demons—we’re made from instinct. Raw, elemental sin. We’re not just creatures. We’re the shadows of temptation, the echo of downfall, the weight of hunger.”
