Naomi noticed.
But the elderly man continued without comment.
Later, she would remember that he had been worried about the bowl before it ever reached the table.
The tea master began the final preparation.
Guests watched as the utensils were arranged and the matcha was prepared with careful attention.
The chairman sat upright.
For the first time all evening, his expression became almost peaceful.
He had loved tea since childhood.
His mother came from a family of growers, and some of his earliest memories involved watching her prepare matcha for relatives during family gatherings.
She wasn't wealthy.
Her family lived in a modest house near the tea fields.
But she treated the ceremony with extraordinary care.
The billionaire had spent decades building an empire, yet he still remembered sitting beside his mother in a quiet room, listening to the gentle sound of bamboo against ceramic.
For him, the antique bowl carried memories that money couldn't replace.
The nephew understood that.
He also knew his uncle would almost certainly drink the final serving.
The tea master finished the preparation.
Naomi received the tray.
Then carried it toward the chairman.
She positioned the bowl carefully.
The billionaire looked toward her.
For a moment, his expression softened.
Then he asked whether she understood why the bowl was important.
Naomi nodded.
"I understand that its history matters to you, sir."
He gave a faint smile.
"History matters only when people understand it."
She inclined her head.
"Yes, sir."
The chairman appeared ready to return his attention to the tea.
But then the nephew leaned forward.
He made a quiet remark about the expense of hiring staff who merely repeated ceremonial instructions.
The CFO smiled.
The billionaire laughed.
And the conversation turned toward Naomi again.
She maintained her composure.
But the nephew's right hand was moving beneath the edge of the table.
The security arrangements had been carefully planned.
Before the dinner, the nephew requested that the restaurant limit unnecessary staff movement during the final tea service.
He described the request as a matter of privacy.
The chairman's security team agreed to keep the main corridor clear.
Only assigned servers and authorized personnel would enter the private room during the final course.
That arrangement made sense for a confidential business gathering.
But it also reduced the number of people who might notice what happened at the table.
The nephew had already obtained a small vial from someone connected to the plan.
He was supposed to introduce its contents into the chairman's personal matcha without attracting attention.
He had been told the substance would cause temporary disorientation.
Enough to create an apparent medical concern.
Enough to disrupt the chairman's next scheduled meetings.
