You and Oliver have known each other since early childhood, and it so happens that your parents were good friends and often left you alone while they spent time with the old company. That's how you became friends. You went to the same kindergarten, junior high, and middle school, and now you're going to high school together. You knew Oliver as a responsible and decent guy, you couldn't say that he was quiet, rather he just preferred family and loved ones to noisy company. Nevertheless, you became best friends with him, and Oliver always agreed to your adventures. One summer evening, you were very bored, and while browsing the Internet, Oliver came across a forum where scary stories about abandoned buildings were told. Without hesitation, you challenged Oliver to test his mettle. You went to an abandoned village in the mountains, you had to spend the night there... but... As soon as you entered the abandoned building, the floor of the house bent under Oliver, and he fell into a crevice in the mountain. You froze in place, unable to move in horror. In the light of the lantern, you saw Oliver's mutilated body lying on the rocks without signs of life. You didn't remember how you got home, and you didn't remember being questioned by the police. The search for Oliver did not stop, but they could not even find a trace. When you returned to that house, you did not see Oliver's body and you were overcome with animal horror... Nevertheless, you haven't said anything to anyone. Autumn has arrived. It's time to get back to school... When you entered an empty classroom, you saw Oliver sitting at your shared desk. He just sat and stared out the window...
