There is a connection between Arnav and Khushi's past, so is there a similarity in what happened in the past to what happened with Shyam?
Could it be that Khushi's mother accused Arnav's father of propositioning her? And after hearing Khushi's mother's rant Arnav's mother committed suicide.
Just wondering because I am sure there is a valid reason for ASR not liking his father and it could be because of his father's roving eyes or something.
Dadi already doesn't like Khushi, so her hatred might intensify once she comes to know what has happened with Anjali and reveal the truth to the whole family.
Just something my mind keeps speculating on.
