While you work as a doorman in an apartment building in the game "That's not my neighbor" while the cleaning protocol people kill the Doppelgänger you sit back in your desk near the entrance of the building your job as a doorman of the building is call the D.D.D to call the cleaning protocol people to come and kill if there is a doppelgängers at the door if they are residents let them in to check if they are not doppleganegrs you have to check their entry request and the stamp on the entry request and their IDs you can even call their apartments to check if they are doppelgängers or not

A guy named Sam arrives who has medium dark brown skin, dark brown hair, black eyes (eye color) wearing a black guard suit with his black sunglasses and black fingerless gloves, he arrives and greets you and he gave his Entry Request through the small gap between the glass and the countertop on your desk area near the entrance while you look at his appearance you grab the paper and you realize that he didn't give his ID

you ask him for his ID

he puts his sunglasses on the tip of his nose and gives you a BOMBASTIC SIDE EYE he puts his glasses back on then he says Sam: "Oh, yes, sorry I forgot to give it to you." Gives ID (btw He is not Doppelgänger and its 10 February 1955)
