In the new promo its shown that Ishwari will be waiting for Dev to go to " Only mother and son " shopping. But this year he will break the ritual and brings it which is of Sona's celebration. Obviously Ishwari will be both shocked and surprised. May be many such tiny issues will happen which may give a feeling to Ishwari that Dev might have completely changed or later she may come to know that this change is bcoz of some girl and may feel that he will change completly after marriage and feel insecure ( of course anyone would feel) irrespective of that girl Sona or anyone obviously she will not like.
