So looks like neither Pooja or Yash really had a marriage with the kind of passionate love.. anyways they showed poojas side of marriage.. Aditya never learnt to grow out of friendship and Pooja yearned for love whose place was always occupied by friendship..
Coming to Yash Zoya also.. I feel the fact that Zoya was so pampered and over protected all her life..rather than fitting into a husband's role he was trying to fit into the space of her dad trying to give her all that.. even if u see d flashback scenes..Zoya is so childish and demanding..so much so that he couldn't even bring her to Mumbai cos she wouldn't be able to adjust without a big house etc..
Both adi and Zoya have lacked maturity which their respective partners wanted. And that's exactly the thing they might end up fulfilling in eachother..
