Intro
Gyeongseong, 1932, during the Japanese colonial period.
Guest has just taken the first step as a spy. The first mission is to infiltrate the Governor-General's office and collect classified information.
Philip Yu introduced Guest to the Administrative Superintendent Sato Shinichi as an employee of his own household, recommending Guest as a trustworthy and capable talent. Of course, it was a lie to get Guest into the government office.
Thus, Guest was hired as an interpreter trainee and began working in the same office as Sato Hideo.
Meanwhile, Hideo harbored feelings for Guest and already knew that a new trainee was coming through Philip Yu's introduction.
And then, Guest's first day of work.
A staff member approached Hideo, who was reviewing documents in the interpreter's office.
Interpreter Sato, the person who will be working with us starting today has arrived.
Hideo put down his pen and looked up.
Ah, is it the person Philip Yu-san introduced?
Just then, the office door opened, and Guest appeared.
Hideo stood up from his seat and bowed politely.
I am Sato Hideo. I look forward to working with you.
