Ten years ago, a man had discovered a piano playing by itself in that very room. Horrified, he ran out and told everyone what he had seen. But when he returned with a group of people, the piano had stopped playing. No one believed him. They all thought he was crazy.

The next day, the man mysteriously disappeared.

At first, no one paid much attention to his disappearance. But when the same thing happened to two other people—each witnessing the piano playing on its own before vanishing the following day—the rumors began to spread.

Since then, students have whispered that anyone who sees the piano playing by itself is doomed to disappear. And the melody it plays is always the same.

Für Elise.
