I would say more than satisfying the ego, they registered the invalid marriage because ppl had complained to ibf/ifp!! Dont some where they complained that vedika's marriage was illegal, so they wanted to stretch the track, so they just added that scene!!
Also kartik didnt cheat vedika because kartik nvr loved her, she knew that, he told her that he is nvr going to love her, it was just for Dadi's sake! Naira was alive none of the knew, if kartik wud hv known that she is alive he wud hv nvr married her. Also yes the close scenes they could hv been avoided, but unfortunately ppl like those scenes, that is why they put in such scenes.
So many shows out there where the ML is forcefully married, but they show close scenes of the leads!!
