The question is about Purvi's izzat. Is it real or mere middle class tomfoolery?
Arjun, you have another girl's ring on your finger, not just any other girl's but her sister's, yet with all pained naivete (note, I did not say nerve or audacity) you asked Purvi today, "why are you doing this to me?" We do feel for you, Arjun, we do know you are hurting but do you seriously expect Purvi to fall into your arms like a ripe plum every opportunity she gets just because you have declared undying love for her? Are you expecting her to say, "Dear Arjun, since you have promised to be mine for the next seven janams (maybe six as this janam is still up for grabs between Ovi and I), we can happily continue with our midnight trysts in the rain while you strut around with that band on your finger. In fact this can continue indefinitely until your dad chooses to return, whenever, from Australia to talk to my baba and you find the opportune moment to tell your childhood obsessed-about-you friend that you can no longer marry her. In the meantime, the girl whose ring you flaunt can drape herself all over you in front of me, I really do not mind as I know heart of hearts that you belong only to me."
Arjun, you would be ecstatic if Purvi did say this for who cares about izzat and all that mohallawalla middle class nonsense. You are Arjun, the first time in love guy, so unreasonably and completely in love, such a die-hard romantic that you truly cannot see anything beyond your love. That is a tad selfish, my lad. If you do get caught with Purvi on one of your masala pav eating jaunts, it is she who will be blamed as heart breaker and home wrecker. Ah, but we should not forget your incredulous question when she asked you on the night of the party about her izzat, "You didn't think that I would let your reputation be besmirched, did you?" Of course not, Arjun, she didn't forget that, neither did we, but you are the one that seems to have forgotten. You were the one that piled her high with those expensive gifts when she was on the verge of being engaged to someone else, so expensive and unwarranted that her fiance-to-be suspected something fishy was going on between her and you. You didn't realize that the world was watching when you asked her to come work with you all night (the MMS fiasco) or when you parked outside her house in the rain, blinking your lights for all the mohallawallas to see. Really, who cares about izzat? What a mundane, ugly word when you are flying high, intoxicated with your newly discovered love!
Yet, the night of the engagement, you had an awakening, you suddenly understood that word "izzat" in reference to your dad and to Ovi, what it would do to their reputations as the world was watching. Yes, we do understand that you love Purvi and you are under the misapprehension that two days of swearing up and down of love everlasting has built insurmountable trust between you (years of love have not done that for her parents) and that you have every right to ask her to abide by your judgement. Just like you expected her to trust your judgement before.
A bit dense, perhaps, on your part?
