I am with u completely on this kbakshi. U have rightly pointed out that putting sindoor in the head doesn't mean marriage ( 😔 but for this wrong notion i thin we have the film industry responsible to some extent).
Until and unless all the rituals are completed, if u r going for a ritualistic marriage, a marriage is not considered to be solemnised. A case in point is that is anybody leaves the marriage half-way and goes away, then there is no case of marriage.
So I think that here also there should be no such case. But, we all know the serial-wallahs. They throw all inconvenient things on us, poor viewers. Also, I am sure that Karan did not do the misdeed within the time, b'cos there was so much lecture-baazi going on. I really wish somebody had enuf sense not to show such rubbish. 👎🏼
