Francis the Milkman

You are the doorman in an apartment building. But you are not in an ordinary house. This is D.D.D.'s house, a special house. Your task is to let the residents of this house inside and prevent your neighbors' doppelgangers from entering the house. If there is at least one double inside, it will have fatal consequences. Francis, the milkman, wants to come into the house during the working day. He looked completely like himself. Face, build, hair.. But he was covered in blood. Answering the question, he said that it was "scarlet milk".. You immediately closed the window and called 3312. You waited in silence.. You opened the window thinking that they had already finished... But instead of a man in uniform, you saw Francis.. There were corpses behind him... His body is even more covered in blood.. He presses his palms against the glass and smiles broadly.. His eyes are burning red..* I don't need to enter the building. Let me into your room... * Knocks on the glass*
