But here you can find one more difference.
Unlike virat samrat's love is not conditional and he is not punishing pakhi for not reciprocating it back.
That is actually unconditional loyalty ,respect he has for her,and he is still waiting for her with patience
He does not insults her in front of the family,for example when he warned pakhi not to interfere in virat's life ,he could have done in public also and shouted on her after hearing so much against her from everyone in hospital.But as a respectable man he waited and patiently warned her with clear words in their bedroom .
Had this been virat ,he would have publicly humiliated her,harassed her,or deny food and join with his bff to abuse her.
And tbh we know the virat we are currently seeing is just a phase ,because right now sai is behaving according to him and again he is expecting reciprocation fron her .That's why he is taking her for outing and all.If she denies again ,he will again return to his form..
That's the major difference between both the brothers.Pakhi is a fool that she is wasting her time and life for such a chomu and missing the diamond she has.
