i am of the opinion that dadaji is fully ignorent of kunal's love towards nats and kun's realtionship with nats , with out knowing whats what this old man has taken nats help telling her that he wants to open kunal's eyes as kun has lost the lost the value of realtionships in life.above all nats would have thought this is a great opportunit to win dadaji's heart as she intends to marry kun!
on the other hand nats might have helped dadaji just to make her man(kun) a better humanbeing she wouldn't have ever thought of kun falling in love with nimo as she has always thought of kun and nimmo being just freinds and she knows that kun will never fall in love with nimmo who is clumsy and less appealing then her with that confidence she allowed kun to be with nimmo .
while dadaji might not have ever dreamt in his wildest dream of nats and kun marrying or kun being in love with nats!
But nats had a strong insecurity bite in the party when kun called nimmo as his wife who is behind his sucess , nats has thought that kun would call her which ddin't happen , nats started having a reality bites that y she insisted dadaji in revealing the truth in that party itself as she wanted kun to be with her !
dadaji's ignorence has created more problems in kun's life then before, its not not just kunal who will be introuble but also dadaji as he has no ill feelings towards nats nor towards nimmo:
so the real test of love and relationship is on the way
