Who is Mrs. Parshuram?

Now, I really have this question - and that is who is playing Mrs. Parshuram in the show? This show is titled as Mr. And Mrs. Parshuram.

They have clearly established that Shiv is Mr. Parshuram, but why do I feel that Shalini is not Mrs. Parshuram, because they are consistent in mentioning she is Mrs. Deshmukh, Shiv's wife! I am in no world implying different wife of Shiv at this point, but any possibility that her character is temporary or would she be the one to play titular role too?

I think she will be revealed as Mrs. Parshuram after a while. She is also undercover as of now. I feel Parshuram is a name both Shiv and Shalini chose as their work name together.

Scenario 1 :- They are really married, love each other and have kids but they are also pretending to be an insurance agent and housewife for now.. may be to solve a long term case.

Scenario 2 :- They may be unaware that each of them is also solving different cases even now after a hiatus from spying to be committed to kids and family may be agreed upon by both when Pihu was born.
