\Completely agree... he thought to ask his father first because he wanted to avoid complications in Suman's life especially... first time when he want to propose he know his father will not have any problem (though that was not the case as he saw NJ nirmala in sumo since the beginning) but today the equation between them changed hence his father not approve or may approve but not happily according to him.. so he thought of taking his approval first than later as at the end of day he has to take permission if now sumo is not have to face any pain of rejection but if after there are chance of rejection of this relation from his father which painful and he did not want to give that pain to sumo...
