We all witnessed of two fathers - both stands part a pole.
DK - He is calm, cool, quiet & compose. He is supportive throughout his son's relationship. He was supporting him like a pillar. When it is the time to face Manav, he consoled his son that he is with Arjun. Nothing is so soothing than a father's assurance that he is with me!!! He can value the love, he knows if Arjun does not tell it, it will destroy three lives forever. Temporary sacrifice can bring life long pain for everybody - he understands this by loosing his love , his wife Ashna.
Manav - he is so loving & caring to his daughters, who means a lot to him. he is a father of a girl who madly love Arjun. he can not control his anger . His all anger falls on his wife. He was helpless. He can not see his daughter's tears. he has lost his all control over his brain due to anger. he was loud, he shouts at Arjun, DK & Archana is front of chwalwalas..ghar ka jhagra pura mahalla jaan gaya!!!
Both are fathers, they both do not see their kid's tears. But..Payaar to kiya nahi jata ho jata hai..
