Once upon a time, in the kingdom of Rimini, there lived a beautiful princess named Nicoletta, who ruled alongside her older brother Riccardo after the death of their parents. This cheerful and witty princess, though wise for her age, foolishly fell in love with a song about the perfect and universally admired King of Salerno. Riccardo, like a loving brother, went to offer her hand to the king, regardless of what he thought of the idea. However, the proud king, spoiled by his mother, insultingly rejected her, saying that she was not worthy of his beauty, but he did not know that Nicoletta's other qualities included stubbornness and determination.
