As per my experience with the lead actors of all most all shows whether it is saas -Bahu or love story, many of them hugs each other and chats very cutly in front of camera to show their deep friendship (?) , then do avoid each other even not in the talking terms once the show over. I hate this type of behavior. I have seen the same between many popular and non popular onscreen couples. I hate this fakeness even though it is enjoyable to watch their off- screen tight hugs😆 (actually it is called off-screen acting, DVD out of this type of reality show acting)
i like DVD as they are cordial each other. It is the actual reality with out any fakeness. In the real life also, we go every day office and spent time about 10 hours with our colleagues, many happy and funny moments happens , but out of the office 99% have different set of groups and different life. That is called professionalism.
The same go with DVD and as per my opinion it is the healthy way to avoid many worst gossips which may have affect their personal life.
At least we can say DVD are honest people unlike others.
