The boy looked at the edge first to see if the clouds were farther away, but... nothing changed.
He decided to go down the stairs. Minutes passed by. He looked over the edge again, only to see that everything was still the same.
'Is this a loop?'
More minutes passed, and still nothing. He kept going, but he was starting to get thirsty again. Then, just below him, sat a bottle. It looked exactly like the one from before. He grabbed it and drank the whole thing.
After he finished, he had an idea.
He placed the empty bottle on the floor. He would go back up to see if the bottle stayed where he left it.
