Once upon a time, there was a royal windmill where the queen and her son, the young King Sebastian, lived. Sebastian was long past the age of marriage, but he was much more interested in his collection of curiosities than in girls and ruling. One day, a simple girl caught the prince's eye at the market. She alone will become queen, Sebastian thought to himself. Little did he know that his chosen one, the kind and diligent Mariana, had a lazy and envious sister, Adriana, and that the two girls, born at the same hour, were indistinguishable from one another.
