Honestly, Emaan, she is too naive or she knows exactly what she is doing. I think her playing the 'innocent' act is just a act, a naqaab. She can't be that stupid to see what is happening with Taimoor is wrong.
I still remember from the promo, Ahad breaking down so Emaan/Ahad marriage won't happen for sure.
I wouldn't be surprised to see if Emaan is there for revenge, against Taimoor and his family.
