One way ticket

Hi guys! I am applying Visa D now and after that i am planning to fly back in Ukraine. And I wanted to spend on onee way ticket since i am married to a ukranian natl and i am applying a temporary residence permit. Will the immigration officers will make drama of it?

I've entered via Borispol many times (in excess of 30) Never been asked about my ticket.
So I guess not is my opinion.
