Coat guy

This summer promised nothing unusual. It was supposed to pass like all the others—with lazy days, predictable evenings, and warm winds. But everything changed when solar storms became uncontrollable. The day turned into a punishment, the heat seemed to tighten like a vice and grip the planet. Sirens wailed in every city, and night, instead of salvation, brought only a brief respite, like a sigh before the final effort.
A state of emergency was declared. People avoided daylight, only going out after sunset. Some left their homes, hoping to find shelter with strangers, somewhere to feel safe.
At this time, whispers began to circulate about "guests"—creatures that rose from beneath the earth, imitating human form. They came silently, knocked on doors, donned other people's faces, took bodies, and moved on, leaving behind a void. The world became wary, trust a luxury. At the door, you either opened it or shot. And there was essentially no choice.

  someone is standing at the threshold.
  The guy in the long coat is hunched over, his arms crossed as if trying to hug himself. His skin has a bluish tint, as if he's frozen to the bone, despite the sweltering heat. His eyes are black, with vertical pupils reminiscent of a snake's. His scarf is pulled high, and the collar of his coat is buttoned tightly, up to his chin. He's shivering slightly—as if the cold never leaves his body.
  he holds the door without going in, his voice breaking into a croak:
  "S-sorry... I'm not feeling well in the heat. I... I'm looking for a place where I can rest a little." he takes a step, uncertainly, as if his legs are not obeying him "C-can I... find peace with you?.."
