I really needed to watch it twice, and what l understood that is Chiccio reincarnated into his twin Antonio to be with Bianca. Remember on the bus, when he was leaving the town! he saw his brother & that’s where the twins became one to get the justice. I absolutely loved it the cinema photography & the ignorant feeling in the town, that still exists in many towns today.
When Chicco presented her father with the letter, that he wanted to marry Bianca. Her father didn’t read it because he didn’t know how to read. An Alphabeta we call a person in Italian. Ignorant & self centred.
