Sandy after chauhan cause of Nk discuss

hey I have a small theory may be as to why sandy is after chauhan for revenge especially Nk family 😆 I think the thing behind the jarokah is her family ashes who were killed in an accident 😆 as far as we know 😆 what if this accident caused by Nk in his younger days😆 he must have been her boyfriend 😆 cause remember in the flashbacks sandy got the news of tragedy from someone she knows😆 but at the same time daddu must have married Nk off to nirmala to make him a better person knowing about the accident ( I got this idea cause of the way daddu talked at kunal accident incident and how he said covering the bad deeds of children without letting them get punished doesn't have any good results). And while this happens sandy delt alone with her grief😆 and daddu getting to know about one surviving member of that family must have went with nirmala bringing sandy to chauhan house where they can look after her. And nirmala might have been school friends and when comming to chauhan house with vengeance as her target she finds her friends married to the man she loves but who turns out to be the person who caused accident Nk 😆so she decided to keep control of not only family but keep whole family members apart as her revenge😉 so how's my predictions 😉

lol looks too crazy...🤣

I don't think that Sandhya and NK have been lovers, otherwise they would definitely have a relation now when NK seems all the time pissed with Nirmala and spending so much time with Sandhya
