Why take advantage of Khan's always?

I need to know that why does everyone take sheltor at Khan's household? Why Myrium came there in the first place when she had other relatives also and why Zoya always keeps on taking their advantage? Just because of their foolishness they landed Dlishaad in the hospital. Slap or no slap I dont know, not in anyone's favor but Zoya should be shown some limit. If not by slap, then by anger or some other way. I just flipped the serial today as I already read the update so did not feel like watching it.

I think the writers think that the audience is foolish . No we are not. So if the show is ruined we will not watch it. As simple as that. Whether KSG is there or not ,a serial should have a nice and a gripping story. After the mahaepisodes when Zoya was buried alive , I thought WOW this serial is something nice to watch . Hopefully they get hold of the story line soon and show us something nice. I really dont know about GUL's way of working. But I watched Geet and I feel its story was very gripping and made the audience glued to the TV sets.
