There is about 30 mins extra in the Italian version, which I've watched, but as I don't speak Italian all was not clear.
Toto does meet with sweetheart;  they still love one another, but she is married (I think to the guy who got belted by the teacher for not knowing 5x5) and Toto moves on... there was something to do with Alfredo's actions impacting on the romance, but that was mainly as dialogue so I didn't get it. I'll ask the guy at the Italian video shop if he knows the story (he had a cinema for 25 years)
