Превод - Сръбски-Английски - dragi moj ti si jedan od retkih koji ostaje pravi...

Hi Maki,
This line is weird:
"you're one of the few ones who remains a true friend"

I'd say:
"you're one of the few true friends I still have"
or
"you're one of the few true friends (of mine) that still remain"
or even:
"you're one of the few friends of mine who remain faithful."

Thanks Lilian.

I corrected.

without the - ..."you are one of few friends..."
