That was exactly the point of my parenthesis...
sub, those we are referring to are thise obscure books (here in Italy the series is called 'Harmony', they can be found at newspapers' kiosks too...or maybe only there) thatusually have pastel covers and the covers inevitably shows some passionate couple and if you still have doubts the title reveals it must be some romantic story... They must be much worse than the one I described here, all about some veeeeery deeeeeeep loooove and probably some jealousy or whatever...
edit: found the italian site at
www.eharmony.it
Some titles to give you an idea:
Blonde Seduction
Prohibited Contact
(you should see the covers of these if you click on that link - featuring naked legs, underwear and hands... now don't imagine a porn, just in a romantic way

)
Browsing further I found
Two hearts and a camper (LOL!)
By chance or forever? (cover features a bench and a couple on a romantic night)
A spark called love
A pure love
Welcome Dr Wonderful (????)
A surgeon to kiss (!!!!!!!!!)
Our cruise
An endless smile
Ok I'd better stop wasting my time (thus avoiding to let you know about the plots...ask if you want transaltions of those

)...Sadly, I think my mum would read those. But maybe not even her...
