It's probably like this: a girl who plays the piano looks down on another girl because she is learning the violin from a blind beggar. The girl who plays the piano is a rich girl, so she often bullies the girl who plays the violin. The girl playing the violin complained to her teacher (beggar), who told her not to give up. Finally, they all have to take part in a competition. The girl playing the piano broke her violin to prevent the girl playing the violin from appearing.
