The Billionaire's Heir I Never Knew Was Mine novel Chapter 28

Chapter 28: Sienna, How Could It Be You?

The quiet hum of the engine wrapped around the car like a soft, steady lullaby, but it did nothing to calm the storm building inside Zachary’s mind.

"Mr. Handsome Zach... If I really lose my job..."

Her voice sounds soft, fragile, and slightly slurred, echoed again in his memory, as if it had settled there without permission.

It didn’t sound like the composed woman he had just shared dinner with.

It didn’t sound like the confident manager who handled guests with calm ease.

It sounded... vulnerable.

Zachary’s grip around his phone tightened slightly, his knuckles turning pale as his gaze drifted toward the tall apartment building standing quietly outside his car window.

Lights flickered behind a few windows, ordinary and peaceful, yet somehow, he felt uneasy.

He could sense her sadness through that brief moment. It wasn’t loud or dramatic. It was subtle, almost hidden between her playful tone and drunken laughter. But it was there.

And for some reason, that bothered him more than it should.

"...can I work for you instead?"

Her words could be heard again, softer this time, followed by silence.

A long, unsettling silence.

"Sienna?" he called her, his voice lower, more serious. "Are you still there?"

Nothing.

Not even the sound of her breathing.

And then the call ended.

Zachary lowered his phone slowly, staring at the dark screen as if expecting it to come back to life on its own.

’She hung up?’ he muttered under his breath.

His eyes lifted once more toward her apartment building.

’Is she alright?’

The question came without warning, slipping into his thoughts before he could stop it.

’Why did she suddenly get drunk...from all the people she knew, why did she call me?’

The car remained still, parked quietly along the side of the road. The city lights reflected faintly on the glass window, casting soft shadows across his face.

For a moment, he considered getting out.

Just walking into her apartment.

Just making sure she was fine.

Just as he was about to make a decision, suddenly—

"Sir, should we go into the apartment complex, or do you want to go back home?"

The driver’s voice broke through his thoughts like a stone hitting still water.

Zachary is slowly returning to the present. His expression hardened slightly, the brief hesitation disappearing as quickly as it came.

"Go back home," he ordered calmly.

The car engine responded almost immediately, the vehicle pulling away from the curb with smooth precision.

Zachary leaned back against the seat, placing his phone aside as if it had suddenly become heavier than before.

Then, he picked up the iPad resting on his lap. The screen lit up, revealing a detailed report.

Sienna Adams.

Her name stood there clearly, neatly typed, simple... yet now it carried a weight he hadn’t expected.

He scrolled through the document slowly, his sharp eyes scanning each line with focus. Her basic information, her toxic family, her education, her career path, everything appeared normal, even impressive.

Front Office Manager at Imperial Hotel.

Efficient. Professional. No major issues recorded.

Yet his finger paused mid-scroll when he saw a gap. A missing piece from seven years ago that remained unexplained.

Zachary’s gaze darkened slightly, interest sharpening like a blade finding its edge.

He hadn’t planned to look into her this deeply.
