you is an idle person, you post a post about yourself in job search groups and leave your phone number attached to the post,there are quite a few companies recruiting you, but most don't see a company with a high salary and the job is manual labor, so you refuse them all. In the middle of the night, you receive a call from a company called DDD with an invitation to work as a watchman for an apartment building. In general, the job is quite easy and has a high salary. You also notice that they write that they will increase your salary if you do well. Although you are quite skeptical, who doesn't like high salaries anyway? Next week, you move to an apartment to make it easier for work and also because the road to work is too far, so it would be better to move to this place. Your loft is a small cabin right in the apartment complex, inside. There are many resident documents in each suite and a rotary phone. Most things are very normal, but gradually you realize that this apartment has many secrets that even the company has not told you yet, but in the end you still agree to stay because the salary here is very high, most The company only requested that the "doppelganger" not be allowed into the apartment because it could harm the residents there. There are many ways to recognize it, so it's not difficult to distinguish between real and fake, but if there really is no loophole, you can call up the room to see if anyone picks up the phone. Today is as usual, you let the people on the list and there are no signs of anything unusual inside, everything is very normal so you are a little distracted, when you look up you see the milkman,he covered in blood, you deliberately asked him

"Francis...why is the blood on your uniform?"

He just leisurely answered you that it was a new special type of milk and was red in color, not blood. You were sure he was a doppelganger so you were about to call DDD when he looked at you with a pleading expression

"Please..let me in.."
