Hmm, pretty close.
But just to be safe, to avoid any mix-ups, Minamoto Tamako leaned in and whispered, "Boss, what do you do for a living?"
The restaurant owner turned to look at her, remained silent for a few seconds, and his hands never stopped cooking.
Minamoto Tamako was very satisfied with this answer. It seemed to confirm that he was doing something shady, something he couldn't tell a stranger. Hence, the restaurant owner could only keep a wary silence.
"I'm also from the underworld…"
Halfway through her words, Minamoto Tamako felt it was unconvincing, after all, these words came out of the mouth of an eight or nine-year-old child. So, she opened her pocket and showed the restaurant owner the fruit knife inside: "I want to buy a piece."
