I am curious to know what happens further
Lol didnt think further Nivu!
Umm, so Pragya finds a letter in her mailbox five years later that has a copy of her wrinkled letter as well as a copy of the senders letter, in which he criticizes her way of thinking that she'll find her soulmate in such a manner. Angered by getting such a pessimistic reply years later, she send him a retortful letter back of how he should have better things to do than be responding to something he doesnt believe in, meaning he has problems in his life whch he cant share with others as well. And then eventually, from passive aggressive letters, they become more thoughtful, deep, emotional and with a lot of soul. He wants to finally meet her, claiming he's fallen in love with her, but she likes how things are and doesnt want to risk the possibility of getting hurt one more time.
With a lot of convincing and bribes, she finally agrees to meet him and it turns out to be none other than her ex-husband, Abhishek Mehra.
Optional backstory-he knew all along it was her, when he recognized her handwriting in that letter. But she had changed her phone number, thhey had lost touch and she wanted nothing to do with him and this was the only way in which he could reconnect with her and still be close to her even if they're miles apart.
The end!
