Arjun-Purvi were married for about 2 months (talk about short marriage)
Before Purvi married Onir, she knew Arjun for like 6 months (3 of those were pure boss-employee relation)
So in the total of 5 months they were together, they celebrated Purvi's birthdayS (notice it's plural )
Unless when Arjun was married to Ovi, he still cherished his ex with a pathetic display of celebrating her bday. There goes his claim in "trying" to make his marriage work. Well I get if people do not want to be with each other, but for the love of god Arjun, don't lie to yourself and say u "tried".
Anyways, the CVs are pulling all stops to be as sappy as possible for a 2 month marriage.
Also what I don't get is, Isn't Purvi an orphan? How do they even know her birth date?
