All Dadi wants is for her children to stay together & with her.
Kaira moved away for 30 days & she almost died of grief. Gayu's family was supposed to move to Mumbai permanently (or at least long term) & no one lost a drop of sweat over it. In fact, everyone was treating it like an upgrade for Samarth.
I still don't get why Gayu's concerns are being presented as unfair. The writing of this show has gone to the dogs.
