what has been shown in the serial is that both Zoya and Asad are trying to make the other person happy by fulfilling their long lost wishes..(salman and sridevi stupidity)
But coming to the core...isn't is utter disrespect on the part of Zoya not to confide in Mr Khan about small but important events occurring around her. Be it Rajveer coming in the middle of night or seeing Imran and Tanveer etc etc..She has always taken him as a fool, If I must say..
The first thing after confessing "so called profound" love is to share each and every aspect. Even Ayan did with his brother, so what preventing Zoya from telling him. Together they can sort out the situation better.
This approach I have seen in all serials with Tulsi and parvati kinds...
i guess it is not practical...In my family if anything odd happens at workplace or homefront, we first bring it to the notice of the other...
The only dialogue Asad has is "najma tumhe mujhe batana tha" "Miss farooqui aapko mujhe batana tha"...
