before i start i would like to say i'm not trying to offend anyone but just to understand a few points so forgive me if i'm wrong.
so here goes
according to indian culture you cant get married to some one else when you are already married which means which means the second marriage is unvalid.
so how come wen tusshar finds out he is sujal ,he is still with charu because by law this marriage was never valid as he is still kashih's husband?
