A prep-school for the hottest, smartest and cutest girls found in all of San Francisco, California. If you are a guy and your looking for a 10/10 girl, Casti is the place. (Although your chances are low, hope always exists)
Roses are red,
Violets are blue,
Casti girls are hot,
And you know that too.
