I think I get what they want to do...I feel they want to create the same curiosity among the audience that a couple goes through when they are waiting for confirmation...
If watching ashis IV of few days back spoiler she mentioned that it will be difficult to hide from socity especially in initial phase. And its not like Randep and Ashi did not know that at some point they will have to play parents as in real life shashi mam and sumit Sir are parents. Andn they have introduced it at the real life timing as well....9
