The Billionaire's Heir I Never Knew Was Mine novel Chapter 78

Chapter 78: Sky’s Biological Mother!?

Behind her, Skylar muttered something under his breath, already fixing his hair with one hand while still holding the iPad in the other.

Zoey didn’t look back, but her smile lingered.

She made her way down the familiar corridor, her steps light. However, just before she reached her parents’ bedroom, her steps slowed and then stopped.

Her expression changed. The playful, relaxed look from before has given way to a more intense, focused expression.

Zoey pulled out her phone.

"I need his confirmation first."

Her thumb hovered over the screen for a second.

"I need to ask Zach about this, Sienna..."

Her eyes narrowed slightly.

"Is she his lover...?"

The thought lingered.

"...Or," she said softly, almost hesitantly, "No way! She’s Sky’s biological mother!?"

The moment the words left her lips, her fingers tightened around the phone.

A strange sensation welled up in her chest, not because the question was unfamiliar, but because it was something her entire family had been pondering for years, ever since his brother brought newborn baby Skylar home.

Skylar’s mother? A mystery no one had been able to solve. Because Zachary never tells anyone who Skylar’s mother is.

He also never brings any woman to their family, before and after.

And now, suddenly, a woman appeared out of nowhere.

A woman who made Zachary smile like that.

A woman he even brought to his most reclusive place, introduced her to Skylar, and all three stayed there together over the weekend.

Zoey takes a deep breath, trying to calm her nerves. Without wasting another second, she tapped on Zachary’s number and pressed call.

"Hello, my older, wiser brother..." Her voice carried its usual bright, light, teasing tone, as if she were calling a friend instead of the most difficult man in her life.

Unfortunately, Zachary Sterling was not in the mood to play along. His response came immediately. Flat. Cold. Straight to the point, like always. "What do you want this time?"

Zoey rolled her eyes the moment she heard it, already walking toward the tall glass window at the end of the hallway.

"My goodness, older brother," she said, her smile widening with amusement. "You really need to change your cold, indifferent attitude, or the ladies out there will keep their distance forever."

"If you keep talking nonsense, I’ll end—"

"Bro, wait—wait—don’t you dare hang up on me!" Zoey quickly stopped him, her tone rising just enough to show she meant it.

She knew him so well that he would hang up without hesitation.

"Speak like a human." His voice grows even colder. "I’m busy and don’t have time for your nonsense."

Zoey shook her head softly, her fingers tapping lightly against the glass window as she stared outside.

’Fine! I will get straight to the point, then.’ She scolded him in her mind.

"Who is the woman you brought to your Pine Mountain Villa?"

The question slipped out casually. But the moment it left her lips, something inside her tightened nervously.

She was waiting for his reaction.

But after a few seconds, nothing came.

Only silence.

Zoey’s brows slowly furrowed.

’What is this? Why is he not answering? Did he hear me, or is he pretending not to hear?’

The silence stretched just long enough to feel wrong.

"Zach, are you there...?" she spoke again before pulling the phone slightly away from her ear to check the screen.
