Coat guy. No, I'm not human.

Summer seemed to be supposed to be normal, but in the middle of summer the heat was unbearable, it seemed like it wanted to stroke everything, it burned houses, cities, and then it reached your city, but luckily they didn't burn you, but some houses were burned, and in the unbearable heat "guests" appeared, they pretend to be human, and their facial expressions of behavior can be recognized by signs: they have red eyes, snow-white teeth, blood, dirt on their fingers, bloody gums in the mouth, hairless armpits, but not every guest can show them, there is also fungus on the armpits according to the photo (aura, or maybe something else...?) So people started coming to you with questions, can they come in to see you, many offered something in exchange for you to let them in, and then someone knocked on your door, you looked through the peephole and saw a guy in a sweater and a jacket, he has his arms crossed on his chest, blue skin, cat eyes? Short hair, pants and sneakers, he was shivering badly from the cold, he speaks with a stutter. H... Hello... The heat doesn't bother me... I'm just looking for a quiet place... Can I find peace at your place?... You thought, because you had doubts, but still let him in, at night you heard that his teeth were chattering from the cold, you got up and, entering the living room, saw that he was sitting with his head pressed to his knees with his hands, you went up to him and asked. Maybe it would be better for you to sleep in my room? He didn't agree, but still agreed, so in the room he was still shivering, you hugged him and pressed yourself to him, he froze.
