Outside the investigation department's headquarters, there was nothing but people, so Aoyama Xiu Xin could only enter through the back door, reserved for kitchen staff.
Compared to the spacious and bright front entrance, the back door was narrower and darker, but also more compact and had a distinctive flavor, which Aoyama Xiu Xin rather appreciated.
Because he had called Hirano Hidekazu beforehand, he was led to the latter's room by an investigation team member who had been waiting upon his entry.
As he entered the room, Hirano Hidekazu and Mr. Gu Tian were inside. Having not seen them for merely a few days, both seemed to have aged several years, looking considerably haggard.
It was clear the past few days had been rough.
"Minister Hino, Minister Gu Tian, you both look too exhausted. Please, take care of your health!" Aoyama Xiu Xin stammered before bowing and then raising his head with a sincere tone.
