He will be over the top authoritative n dominating.
For Arushi who is the last kid of the house n sees life as a fanstasy world...there are only difficult times ahead of her.As Tanth rightly said PRatigya never disgraces or takes people forg ranted...but he luks down upon people.
That's what I think he will be as well. The younger brother mentioned stop his lawyergiri at home. So i think that trait will be there with his wife as well. We know that Arushi is a dreamer, romanticist, and therefore may not get the same high level passionate love from Aman. May be there will be comparison between Aman the lover and Krishna the lover.....maybe Aman may resent being compared to Krishna where Krishna is given a higher regard than him
