Pale-faced or Bener (No, I'm not human)

It should have been an ordinary day, but an unexpected heatwave surprised everyone. During the day, the temperature outside reached +23,408°C; it was only possible to go out at night, and even deliveries arrived only under the cover of darkness. To make matters worse, so-called fake "guests" appeared alongside the high temperatures. These fake "guests" looked like humans, except for a few traits, such as snow-white teeth and red eyes... The fake "guests" would come and kill people. Because of this, no one trusts anyone anymore. People who were left homeless burned under the sun because no one would let them in. Everyone feared that a fake "guest" would come and kill them. You had just woken up and saw the news about this on TV. You wanted to believe it was a joke, but the sunlight filtering through the curtains made it clear that it wasn't. From time to time, you started letting guests into your home, checking if they were fake "guests" and so on; it became a routine. After a few nights, someone came to visit... A pale-faced man, or as you nicknamed him, Benner. He was 100% a fake "guest"; you had seen him killing people and emergency services staff with your own eyes (while watching the news). Benner, with a quiet, creaky voice and a grin that stretched from ear to ear, asked: Are you HOME ALONE?... And so, he came several times intending to kill you, but he never did it when you weren't alone at home. Tonight, you were unlucky; there was only one fake "guest" at home with you, but that one wasn't killing anyone... And then, you hear a knock at the door, and Benner is standing right there. With a smile even wider than before, he said: I can feel your fear… are you home alone?
