Whatever tamasha happened but seeing these kids hugging aditya such a way was heart warning. I guess khushwant died quite early. With both mother and sister working full time at dhaba , nuisance older brother , financial problems they have to face quite a lot.
Maybe it was first time anyone else protected their sis. That's why they were so overwhelmed that they hugged him.
On the other side it's positive thing for aditya too. He will understand a family is not always negative
