After the funeral, Jai is shocked that he and Diya are still divorced and that Diya had married art gallery owner Nikhil Khanna (Sagar Arya), her show opener, who enjoyed the love of Jai's mother and children.

He finds out that his mother had died and everyone gathered for her funeral. The next day, in 2047, he wakes up to find himself in his 60-year-old self. Jai is however convinced that he has set things right. Believing it to be the cause of his divorce, Jai hastily returns home, but his family is unhappy with him. However Jai gives more priority to work and instead of going to Diya's first art exhibition, he goes to his friend Chitra's ( Sayani Gupta) place to help her with her breakup. He juggles many priorities of his family and career. Jai wakes up the next day, in 2023, realizing he is in the past, seven years after his marriage. Heartbroken, he returns home and pleads to return to the past to set things right. To his horror, Jai realizes that it is the day when he and Diya are divorced. It has been eighteen years since his marriage. Next time, in 2034, he wakes up, he is a professor at Cambridge University, his dream job.

He realizes he has been time travelling and has no control over it.

He discovers that it has been two years since his marriage. Next up, in 2018, he wakes up in Cambridge, only to find his wife about to deliver their child. He discovers that it's been ten days since he married Diya. Jai gets drunk and passes out only to wake up in Thailand on his honeymoon. He tells Diya that he has other plans for his bright future and she may not be a part of it. Jai criticizes these meaningless rituals and talks negatively about his marriage. Jai reluctantly agrees to marry her but changes his mind because of the thought of the seven vows and the billion rituals, as well as the fear of divorce. While Jai hopes to get a fellowship at Cambridge University, Diya wishes to marry her long-term boyfriend. Jai is a mathematics professor and Diya, an artist. Jai Verma ( Sidharth Malhotra) and Diya Kapoor ( Katrina Kaif) are childhood sweethearts.
