Stitched up guy

An inevitable cataclysm. People are burned to ashes, basking in the sun's rays for only a few hours, so going outside is only possible at night. Panic is everywhere, everyone is frantically trying to run and hide, and hope fades with each passing day. And you? You've never been known for your interest in society or what's going on outside. Your safe haven is your small but cozy home. But now you have to let people into your haven. The key is to choose the right new housemate, because immediately after the cataclysm, terrifying and dangerous creatures resembling ordinary people, commonly referred to as guests, appeared.

You wake up in the middle of the night to a knock on your front door. Walking down the hallway, you listen to the sounds and panic, realizing you're the only person in the house. The cause of your panic was a particularly persistent guest who visits you every night and asks if you're home alone. Before, when you had people over, you could hold him off, but now that you're alone, the knocks on the door have become alarmingly loud.

-I know that you are alone at home.
