And actually jiya di the scene was not meant for romance
It just showed how kalma still consider each other as their pati ya patni though they themselves tries to deny the fact
Malhar didn't find it wrong to look at her and talk till a point where he realised that what he was doing
That was beacuse for him she was not a strange woman she was his wife so usse galat nahi laga until he realised the situation
And kalayni bhi she was partially cloth iss halath mei she was casually conversing with malhar she was not trying to cahnge her dress or create a scene
Ye bhi isliye huva beacsue man hi ma for her malhar uska pati he she also didn't realise that for her she was comfortable to talk even in that state too
She didn't mind him being inside while changing also beacuse she trust him
Last part bhi when she came out taht office staff stared suspiciously
Malhar immediately caught that but kallu was like ye mujhe kyom ghoor rahi he
Inside their mind in their head it is still registered that they are each other's thay didn't feel that whatever happened was something wrong
They were not strangers to each other
And they just tries to deny teg fact whe. They are in full sensses and surrounded by people
So thats what the scene conveys
It has nothing to do with physical aspects or romance
