Already there are many negative and shady characters in the show...What this show needs is some lighter, fun moments and for makers to stick to the actual concept
Pooja-Arjun is a big NO for me...coz it would mean Zoya was right and she will remain the kind of person she is while Adi will never be able to trust anyone...He is heartbroken over his wife's betrayal..even his dad had an affair so now if Arjun also had an affair then this will be the last nail in coffin for Aditya
Show was about how two people will realize that their marriage was not perfect and then they will move on and re-discover themselves and fall in love again.
Also so far what has been shown will not make sense then...I have already posted how Pooja if had Adi as a hubby , Arjun as a bf then why the hell would she form a close emotional bond with Yash...3 men in her life...A husband. a bf and a very close friend 😕 It doesn't make sense at all
From story point of view we need the story to move in the present as much as possible...AdiYa progression...Arjun-Noor...later cute bhabhi devar moments between Arjun-Zoya...scenes of all 4 together...lighter moments in the show...rather than betrayal, sadness, dark and depressing episodes with a lot of villains
Also even when Arjun is alone he addresses Pooja as bhabhi 😕 Pooja-Arjun will be very very awkward and unnecessary...I won't be able to enjoy the show in that case
