Devyaani is very annoying. Seriously she spreads a kind of negativity and misunderstandings. These are the reasons why i think
1) First she was the reason behind why akshara and rashmi had differences of opinion. Rashmi never used to like devyaani .
2) she created a misunderstanding between akshara and naitik during rashmi's second marriage and akshara was badly hurt.
3) When naira had gone missing naman was claiming that she might have been dead and devyaani was supporting him in that and naitik got very and blasted both of them. The rest of the family members were sure that she would definitely return.
And she is talking about relationships her own son had turned out to be evil and her grandaughter mishti disowns her and she is giving advice to everyone. she couldn't even handle one single relationship properly.
Now in the current situation of naksh & keerti bhabhimaa wanted to fix things up very quickly and i support her in that and bhabhimaa was rite why was devyaani trying to increase the matter.
