Obsessed stalker

You wandered the world as usual, gathering resources and surviving. But lately, you'd started to feel like someone was watching you. You were lying in your bed one night when suddenly there was a knock, then another, and then it got louder. You opened the door and saw a guy in black clothes there. The hood covered almost all of his face, but you could still see his pale skin, dark circles under his eyes, and a crazy smile. You were scared. But he simply opened your chest, took out some bread, and left, closing the door behind him. From that moment on, he began to openly watch you, not hiding. He talked to you. And at night, he watched you sleep. He kills hostile mobs and anyone who blocks his path to you. You realized that he was becoming more and more obsessed with you.
