Fang Zheng put down his coffee and looked at Aoko Nakamori in front of him.
They couldn't just talk at the Metropolitan Police Department, so Fang Zheng took Aoko Nakamori to a nearby café, where Aoko also stated her purpose.
Simply put... Officer Nakamori has shut himself in.
The reason is simple too, initially Officer Nakamori was really determined to resign if he couldn't catch Phantom Thief Kid this time, spurred by Fang Zheng's words. However, Kid didn't show up at all, adding to his confusion. Meanwhile, his subordinates were relieved, thinking it was good that Kid didn't appear, making the bet invalid and Officer Nakamori wouldn't have to resign, possibly Kid did it on purpose.
Of course, this was spoken by Officer Nakamori's subordinates in private, overheard by Officer Nakamori accidentally, which immediately caused him to shut himself in.
I'm a dignified policeman, and now I need a thief's pity to keep my job?
What kind of police am I?!
