The Billionaire's Heir I Never Knew Was Mine novel Chapter 19

Chapter 19: It’s Just Curiosity

A gentle sigh could be heard from the other end of the line, carrying a charming, childlike sense of drama.

"Dad, you said you would help me with my math problem," Skylar said, his tone full of quiet protest. "I even texted you... like... three... No four times."

Zachary exhaled slowly, guilt settling in almost immediately.

He really had forgotten.

"I’m sorry, Sky," he said, his voice gentle, sincere. "Dad got caught up with something."

"Something more important than me?" Skylar asked, his tone suspicious.

Zachary almost smiled. "Of course not," he replied immediately. "Nothing is more important than you."

There was a small pause, as if the boy was considering whether to accept that answer.

"...Okay," Skylar said at last, though his voice still carried a hint of doubt.

Zachary glanced at the time on his dashboard. "I’ll be home in thirty minutes. We can still go through it together."

On the other end, a soft yawn slipped through.

"...But if you’re sleepy, we can do it tomorrow morning," Zachary added. "You need rest."

Another pause before Skylar’s voice came through once more.

"It’s okay, Dad," his voice softer now, almost drifting. "Arthur already helped me."

Zachary let out a quiet breath of relief.

"Did he?"

"Yeah... but he’s not as fun as you," Skylar added honestly.

That made Zachary smile, though the guilt didn’t leave.

"I’ll make it up to you tomorrow," he said. "Deal?"

"Deal..." Skylar murmured.

"Alright. Go to sleep now."

"...Okay. Goodnight, Dad."

"Goodnight, Sky. I love you."

"I love you too, Dad..."

After the line went quiet, Zachary inhaled deeply.

The car continued moving through the night, heading fast toward Lakeside Garden.

But something felt off. A quiet discomfort settled in his chest.

He had never broken a promise to his son before.

And tonight. He had.

Zachary tightened his grip on the steering wheel, his expression turning thoughtful as he drove through the quiet night streets. The city lights passed by in soft streaks, reflecting faintly on the windshield, but his mind was no longer on the road alone.

The warmth from earlier—the dinner, the conversation, the way Sienna had smiled so naturally—still lingered somewhere inside him.

But now, it was mixed with something heavier. Something he couldn’t easily ignore.

The silence in the car stretched longer than usual.

Then, without hesitation, he reached for his phone and pressed a number on the speed dial.

It rang only once.

"Hello, Boss. What assignment do you need me to do?"

A man’s voice came through the phone speaker, low, steady, and far too ready.

The tone alone made it clear that Zachary’s calls were never casual. When he called, something always needed to be done.

Zachary didn’t waste time.

"I need you to investigate someone," he ordered calmly.

There was a brief pause on the other end.

"Name?"

"First name Sienna, last name Adams. She currently works at the Imperial Hotel as a Front Office Manager."

This time, the silence lasted a second longer.

Even through the phone, Zachary could sense the surprise.

"Something more important than me?"
