I think he slaps her for another reason. If you recall, the girl's mother (i forgot all of their names) was worried why she is going out really late in the night....something like that. Then maybe her boss thought she was a good shareef girl and was only testing her to see if you would really come. So he probably was shocked that she actually came and he probably didn't think she was that kind of girl coming really late to her boss's house i mean you know and slaped her..... OR I'm totally mistaken and he slapped for some reason that i have no idea. :/ I don't see a reason why he would slap her other than what i htink it is because then it make him think she really is stupid and if he was not he rboss and any other guy suppose her brother's "debt collectors" who called her she would have even gone then. I'm guessing.
the drama is going well so many secret and story yet to unfold i think but I htink fahad mustafa needs act a little bit better. It's as if he trying to act the character (it's so-so or maybe he will develop his character more later?) I remember watching moorat and kashif mehmood was superb!
ooo you might be right...lets wait and see. as for fahad's character yeah his character is a bit slow...aur woh hur waqt bus rota rehta hai...like all the episodes i have seen so far...all he is doing is just thinking and mourning.
