Well for Afreen i can see that she wants Azaan to be happy and thinks that Saniya is his happiness, thats why she is not confessing and wnats to leave him...
but what about Azaan, only on this basis that she loves Kabir he cant leave her alone being pregnant when he is pretty much aware that Kabir is not alive and he can fill his place in Afreen's life, not too sure wht's his problem in confessing..he can say taht "Afreen i dont know if i can be Kabir Bhai but i also love u more than my life"....why not....such a loser.. 😡
