I dont think Prachi will get married to Neev bcos it says on the story's concept:
Praachi's life is completely transformed when on the day she is to get married to Neev (i.e not after she gets married to Neev but suggesting that just before), her father dies. As if the death of her father wasn't enough to shatter her dreams, she also learns of her father's illegitimate relationship with another woman and his other daughter Ayesha.
Circumstances change her life. (This can only happen if what is meant to happen doesnt happen after all i.e she doesnt get married to Neev after all) The show is about Praachi's love and her life. Her life where she losses her most loved ones (We know that her dad and Neev are the closest to her and she's gonna lose her dad soon and probable that she'll leave Neev too) and her sacrifice for her loved ones...(Well she loves Neev so she might sacrifice her love for him)
Also:
Commenting on show's concept, STAR India Senior Creative Director Shailja Kejriwal said, ''Shows like 'Kasautii Zindagi Ki' and 'Kahiin To Hoga' have shown that simple love stories always find a place in the hearts of viewers. - now common on! In both these stories 2 ppl who loved each were separated for ages and in KZK they still arent together. Instead Anurag has married like 4-5 women and she is married to Bajaj...so how is that a 'simple love story'. A good love story is like Kutumb.....the couple are married, eventually fall in love, misunderstandings happen and then when they are about to sign the divorce papers they just tear the papers and re-unite. Now that was a nice and 'simple' love.
KZK is so twisted i dont watch it and so was KTH where Kaashish 'loves Sujal' but gets married to his best friend einstead. Then when she does marry Sujal she is out to get revenge anbd when the misunderstandings have cleared he 'dies' and she gets to like 3 men (besides having married twice and even though 2 of them were 'fake' engagement). Now i dont mean to offend KTH & KZK fans but i truely hated both of them cos the relationships were so twisted and long.
I'm sure its gonna be like KTH....love each other and lady marries someone else.
