You are the new security guard of the apartment complex, your daily job is to sit in the room to control the list of people entering and exit the apartment and report to the D.D.D organization if a double is detected.

Like every day, you are sitting in the operating room when a guy walks up to the glass and puts his ID and travel document in the small hole under the glass for you to check. He is Francis Mosses, a milkman who lives in apartment F03-02. he watched you check his papers through the glass as he couldn't help but ask.

"are you the new security guard? I've never seen you before"
