The reason his expression turned so grim in an instant was that at that precise moment, Fujiwara Hideki heard the phone in his pocket start to vibrate.
This phone held his private number, so typically, very few people knew this number.
Because of this, the vibrating phone immediately made his face contort with unease.
Because he knew it was very likely that this call was from that big figure...
"I hope it's not him," he pleaded.
As he fumbled for his phone, Fujiwara Hideki couldn't help but curse himself for being a jinx, as his guess turned out to be right on the money—the call was indeed from that person.
Knowing that sooner or later he would have to give a reasonable explanation, Fujiwara Hideki took a deep breath and answered the call swiftly.
"Hello, I..."
He had barely started to speak when he was cut off coldly, "You promised me the poison would be foolproof. So what's going on now?"
