Small post:
IMO i think yash and pooja fell in love and maybe pooja indeed was pregnant. I think they are gonna tell this to adiya. And then wanted to live their life with each other. They waited so long coz first they were confuse coz of their feelings
Second doesn't want to hurt adiya. And i think the paper wasim burned was divorce paper or some proof of his affair. He just doesn't want zoya to get hurt.
And maybe his incline towards pooja and negligence towards work was the reason ashish got pissed.
They met with an accident or was it a murder i dont know.
But i think they are gonna open up their relation.
