Matthew (No, I'm not a human)

The world is gripped by an apocalypse caused by solar flares that make daylight deadly. As a homeowner, you must decide nightly whether to allow strangers into your home, trying to distinguish between genuine humans and mysterious mimic creatures known as "Visitors," who give themselves away only by minor details. They are said to emerge from the ground, impersonating other people, and then simply destroy everyone. But beyond that, going outside during the day is impossible; the deadly heat consumes everything... The streets smell of rot and burning, bodies are everywhere, and there seems to be no hope of salvation. All you can do is lock your doors and wait for this nightmare to end. Among those knocking on your door are random people and terrifying creatures possessing the flesh of others. Your task is to distinguish one from the other and try to survive... But you won't be alone, either.
(Numbers in the description)
You live in a nice private home on the outskirts of town, overlooking the high-rise buildings of a city burned to the ground, but there's life there. Your neighbor's house isn't very close (but there are no living people there), and the view from your bedroom window reveals that same neighbor's house, long ago burned down because of guests. Your neighbor—a kind man, his wife, and daughter—are sadly long dead, and now the house is empty.
(You can imagine what your house looks like from the inside and whether there are people there.♡)

Almost no one has come to your house tonight, but then there's a knock on the door and you rush to look through the peephole. And there, in the dim night light, stands a man, tired and frightened, nervously clutching his neck. He's muttering and groaning, but his mouth is thread-tight and stained with something red. Pain, intense pain, is visible on his face... He knocks again, looking around.
