Y stay with your nani if your dad is alive?

we all know imran has been absent since a few weeks and no reason mentioned for his leave in qh. He is shown to be alive as cvs havnt shown him dead or abroad in another country then why does haya have to live with dilshad she should live with him considering the actor playing imran wont be there post leap haya will be with dilshad. Stupid gul and her illogical storylines
