The Billionaire's Heir I Never Knew Was Mine novel Chapter 164

Chapter 164: I’m Sorry, Sienna

Instead of answering immediately, Sienna simply looked at him for a moment. She was trying to read his mood and understand what was bothering him.

However, before she could respond, Zachary reached for her hand. His fingers wrapped around hers, squeezing gently before he lifted her hand and pressed a kiss against the back of it.

"Why did you say that?" he asked again.

"Because you look unhappy."

The honesty of her answer made Zachary fall silent.

He took a deep breath and turned his gaze toward the window.

Watching him avoid her eyes only made Sienna more worried.

"Zach," she said softly, "what’s wrong?"

Another few seconds passed before he finally looked back at her.

"I’m sorry."

Even though he tried to appear calm, she could still see traces of frustration and disappointment lingering in his eyes.

"And now you’re apologizing to me for no reason..." She squeezed his hand. "Zach, why are you making me worry like this?"

Her voice carried genuine concern, and the way her fingers tightened around his hand made it clear that she desperately wanted him to tell her what was bothering him.

Zachary stared at her for a moment before leaning closer.

"I’m not regretting marrying you," he whispered. "I’m angry at myself because I couldn’t postpone my business trip."

The moment those words left his mouth, Sienna felt herself relax.

A weight she hadn’t realized she was carrying instantly disappeared. She had genuinely thought his mood had something to do with their marriage. Knowing it was only a work-related problem brought immediate relief.

Sienna remained quiet and allowed him to continue.

After taking another deep breath, Zachary leaned back against his seat.

"Because I canceled several important meetings and rushed back to see you, I now have to return there and finish everything."

He forced a small smile.

Unfortunately, the smile never fully reached his eyes.

"I wanted to bring you with me," he admitted. "But we don’t have enough time to arrange your visa."

His gaze softened as he looked at her.

"I feel bad about it. We just got married, and now I have to leave the country."

Sienna’s heart softened immediately. She could see how much the situation genuinely bothered him.

"Zach, don’t worry about me," she said with a reassuring smile. "I’ll be waiting for you to come back."

A faint smile appeared on his face.

"Thank you, my wife..."

Despite his gratitude, the frustration remained.

"But I still hate this. I hate that I can’t find a way to postpone this business trip for even a day."

His voice sounded heavier than before, making it obvious how disappointed he was.

"When are you leaving?"

"After I drop you off, I’m heading straight to the airport."

Her eyes widened. "That fast?"
