One day, all of a sudden she was sent a letter to attend a school for rich kids only with certain backgrounds. The ordinary girl turned from poor into a whole new world. She encounters these handsome boys along her way. The richest, the juvenile reputation, the popular and more. In the end, which one does she choose to be with?
