Tecla tre volte

There is a cube. A cube that makes it possible to rewind time, erasing mistakes, misunderstandings, and wrong choices. But it can be used only three times—after that, it stops working. Nazario Mazurca has kept it hidden in his cellar for twenty-four years, ever since he received it as a child from a mysterious man who claimed to come from the future.

Now Nazario is grown up: he is the singer of a Genesis cover band, and he has fallen in love with Tecla—something like Gloria Guida, but with a librarian look. Despite the wise advice of his best friend Amelia, Nazario keeps getting something wrong in his relationship with Tecla, until he ends up causing their breakup. But Nazario has the cube. He can rewind time and erase the mistake, overcoming the obstacle.

Will he manage not to mess up more than three times?
