A diary of a small girl, with big dreams Will she succeed?

(very old!) zodiacs </3

The title pretty much sums it up.

Rosa is a well behaved child, she gets good grades, but she's a bit of a goody-too-shoes. One day when Rosa hears the people who she calls 'her friends' talking about her behind her back for the first time in her life she doesn't know what to do. Will she become cool so that she forgets who she is so that her 'friends' will like her again or will she just be herself no matter what other people think.
