welll i read the family treee of rrk401...and it cleared my doubts as i mised 1st episode...
well in her post i saw lots of post asking did so much for mooh boli sis(adopted sis)...so here is my analysis why this man is doing so much for this moh bolli sisi...
this property belongs to shereen and there was no one to take care of sheeren...and ofcourse the property...so this mooh bolaa bhai steeped in took care off her since child hood and kept evrythign intact and then shereeen married might have him in trouble as her hubby would take evrything away from under his nose(mamu jaan)...so he agreed for sheeren and rashid marrige as he got hsi weekness of having life of upper class...and he blackamiled him for it and in return he(mamu) was geting all the hold as rashid too became servant of him(mamu)..now all house hold in his hands...thats why rashid mom said to mumeereee jaan all thouse stinging words as they both standing on same boat(rashid mom and mamu wife)...😆
