I have a strong feeling that Riya's adversary in Shanti Sadan will be none other than Kaushi.
From yesterday episode it seems like Kaushi will b trained by Shanti on how to deal with daughter in law. I have a feeling that Shanti will not do anything in front but will instigate Kaushi from behind. Kaushi being a person who believes that elders need to be respected and listened to will do whatever Shanti says.
I was looking forward to Kaushi and Riya against Shanti but not sure anymore. Does anyone else feels the same
