I have a feeling that Yash is alive.. and probably staging everything... My reasons as below..
1. Why Pooja ditched adi was mentioned in the diary.. some day for sure adi will get to know what issues Pooja had in the relationship.. but how will Zoya ever get to know d truth of why Yash cheated her..
2. Mahi is involved with Yash in all this.. may be the debt was a reason behind him staging all this..so that he can get away with everything including Zoya.. and whatever he has been doing is to get the bankcrupcy money.. cos zoya is constantly not letting it happen.. he will frame her with adi.. this rajveer is probably Yash friend..cos if he is a officer and just investigating, why is he hell hell bent in proving they are a couple and get them married.. I guess he even staged the divorce papers so that Zoya gives up on d company..
3. Only Yash can underground his friend so that Zoya doesn't get to know d truth..
4. Only Yash knew that sakshi knew about their relationship.. so he blackmailed her for money..
5. Pooja diary had papers missing.. although rest of her thoughts and secrets were written in the diary and they dint go missing..what was it that was torn off? I guess stuff she wrote about Yash life in d diary..
What's ur thought guys..
