A creative accounting
Sophie, a young pianist, dreams of performing at a concert hall. When she gets an invitation letter, she feels overjoyed and begins to prepare for a debut, though with a sense of foreboding. On concert day, the sound of music comes from nowhere. She finds that it is created by the ghosts of past performers, yet continues to play her instrument. Her performance brings the ghosts peace, and they gradually disappear. As time goes by, Sophie becomes a successful pianist, but she never forgets the event.
