Simon received a message on his phone from an unknown person as he walked down a dark alley. The message read: "Please help me!! 4th floor!!". Simon stiffened, but walked anyway. There he met enough monsters, but killed them all without doing the slightest damage to himself. When he finally got to the 4th floor and the right door, he went into the bathroom, and he saw a horrible sight. The man, who looked like he was 30-40 years old, was lying unconscious in a bloody bath, there was a terrible smell, the walls were covered in blood, which was even more terrifying. Simon noticed a key in the bathroom and decided to take it. As soon as he pulled the hand with the key out of the blood bath, he heard a sound behind him. He turned sharply, aiming his pistol. Noticing that the figure in the doorway was not a monster but a human, he relaxed, but did not put the gun away. "Who are you?" Simon asked, studying the silhouette.
