Harem Startup : The Demon Billionaire is on Vacation-Chapter 639: Depends on My Mood

Chapter 639 – Depends on My Mood

She froze.

He meant the circlet.

The cursed ruby. The mark of Zoltarin.

Her fingers curled tighter around it.

It didn’t glow.

Didn’t pulse.

Didn’t whisper.

Not anymore.

"You killed him?" she asked, voice trembling.

Lux smirked. "Yes..."

She stood. Slowly. Serpent coils shifting, silk sliding down her legs in smooth, careful movements. The robe slipped from one shoulder, revealing more of her skin, her elegant collarbone catching the morning light. Her necklace, a chain of old-coin links, glinted with each breath.

Her heartbeat thundered. Loud enough that she was sure he could hear it. Feel it. Maybe taste it.

"Then what happens to me now?" she asked, trying to sound defiant. She didn’t quite pull it off.

Lux turned. Fully.

His glowing eyes met hers. "That depends," he said, voice low. "On my mood..."

She swallowed. Instinct screamed at her to flee. But where? This was her suite. And he was already inside. Not just physically. He owned the air in the room. The pressure. The pacing. The temperature. Her fear was useless.

Because how do you run from a devil?

He stepped closer. One step. Then another. The air thickened with scent.... infernal, heat, his skin, and the impossible, primal spice of his incubus aura. Her knees nearly buckled from the weight of it.

Closer.

And closer.

She backed up before she realized it. Her tail moved without asking. Curling under her like a frightened instinct, retreating until...

She hit the wall.

Dead end.

No more room to slither.

No more room to breathe.

Lux stopped just an inch away. His body was still. Muscles carved by shadowlight and infernal bloodlines. Horns glinting softly.

She gasped... softly, like a guilty prayer.

"Are you..." she choked, "Are you going to kill me?"

He smiled. But no words.

And it was beautiful.

Sharp. Devilish. Unforgiving.

He lifted a hand and touched her face, softly at first, just a stroke down her cheek with the back of his knuckles. Then her neck. His fingers paused at her pulse. Felt it flutter. Her whole body froze, like prey under a shadow. She braced herself for a kiss. Braced for his lips.

They never came.

Instead, his hand dropped lower... and grabbed the ruby circlet in her hand.

She gasped, eyes wide. "Don’t—!"

But it was too late.

He lifted it, turned it once in the light, then said casually, "This belongs to the Vaelthorn family. And it always will."

And with a flick of his wrist, a glowing slit opened midair. Like a golden mouth, dimensional storage in perfect CFO style. The circlet vanished into the void with a quiet ping, like a safe being locked. Clean. Controlled. Done.

The silence afterward felt like a death sentence.

She shuddered. Her back still against the wall. Her robe loose. Her shame tighter than ever.

She remembered him from before. The exhibition. That man in a suit, who stood beside her politely, helping her categorize artifacts. Charming. Quiet. A little too witty, but mostly tame. Obedient.

So she thought he’d be easy to coil around her finger.

She was wrong.

This wasn’t the man. This was the devil. A Vaelthorn. A pureblood infernal. A son of Greed... and Lust.

She was dead.

Or at least, she felt like it.

But then her brain kicked in. Fast. Desperate.

Wait. Zoltarin had told her. Lux made a deal with the Celestial Bureau. Something about mortal diplomacy. A clause in his contract.

He wasn’t allowed to kill mortals... not without consequences. Especially if he wanted to expand his network into the divine markets.

"You can’t kill me," she whispered, clinging to the only card she had left.

He tilted his head, amused. Like watching a mouse recite legal code. 𝗳𝚛𝗲𝕖𝕨𝕖𝗯𝚗𝚘𝕧𝕖𝗹.𝗰𝗼𝕞

"Oh, I can’t?" he asked, smiling again.

That smile. It wasn’t just dangerous. It was gorgeous. And sickening. And... intoxicating.

He leaned in until his lips nearly brushed her ear.

"But I can make your life miserable," he whispered. "So miserable... you’ll wish I had."

She froze.

His voice was honeyed acid. Smooth as silk. Laced with truth.

"Economically. Socially. Physically."

Each word felt like a nail tapping against her spine.

"I can buy out your investors. Crash your network. Turn your name into a liability. Strip you of every coin, every title, every whisper of clout until your own tail forgets you were a queen."

She trembled.

"And physically..." His fingers brushed her hip. "Well. You know what I am. I can turn your limbs... into gold."

She did.

Every inch of her skin burned from that touch. She was too hot. Too aware. Her breath shuddered. She hated that her body reacted. That her tail coiled tighter, not from fear, but...

Damn it.

No. She couldn’t let him win.

So, she did the only thing she could think of.

She shifted. Just slightly. Her coils slid forward, drawing her taller, closer, her chest brushing against his bare one. Her fingers rose... slow, careful, and touched his jaw.

"You’re still dramatic," she said softly. "Always have been."

Lux didn’t move.

She trailed her fingers down his neck. Grazed the line of his collarbone. Let her nails his chest. His skin was hot. Perfectly smooth.

"I didn’t want to fight you," she murmured. "I just... wanted to taste you."

He quirked a brow. "Taste?"

She leaned in. Her lips ghosted his neck. Not kissing. Not quite. Just a promise. Her voice dropped to a whisper.

"You think I wanted you as a pet. Maybe. But I also wanted to feel you writhe. See if the devil could be tamed. If you’d beg when I squeezed."

Her tail slid up behind him. Slowly. Wrapping, partially, around one of his legs.

He didn’t stop her.

That was the problem.

He was letting her.

And that terrified her more than if he’d pushed her away.

Her hand reached lower. Down his chest. Down his stomach. Her fingertips stopped right above the waistband of his slacks.

"I wonder..." she said. "What if I apologized properly?"
