תרגום - רוסית-איטלקית - Ты очень интересный молодой человек, мне приятно...

My Italian is far (faaaaaaar ) from perfect, but may I suggest >>> mi piace frequentare con te, spero che sia reciprocamente.

"Sono lieto" fits the meaning too.

"frequentare" means rather "to attend" so I wouldn't choose the verb, but your "spero che sia reciprocamente"...maybe, maybe...

Almost, it's "..spero che sia reciproco!"
