This is a fairy tale that happened on a desk. The little toy pianist fell in love with a music box ballerina who is sealing in the glass bell. However, he couldn’t wake her up because the key of the music box was lost. Therefore, he made up his mind to take his own clockwork to charge the energy to the music box, which cost his life. But the fantastic thing happened: the ballerina is actually a fairy. She saw the keyhole behind the boy so she raised the boy with magic. They finally lived happily together.
