I guess its the high time for Ayan to return, Humi is all turning into Razia part 2, and if ayan will enter at this point of time, she gonna torture him like anything with all her linkups with Haider...
even Asya now getting married soon, Don't he want to attend his brother;s wedding which was not happened last time due to him only.
he is kind of the person which takes him ages to create his own identity, it will be Asad only who can give him some work and settle him in his life...so its high time for his return.
