why did tanu's father and rishi's father never had contact for all these years...why should tanu be made to wait hopelessly for 15yrs...they could have been very much in touch with each other with phone calls,video calls,emails etc ... why only after 15yrs suddenly they should get to know that rishi has married a firangi :P...
logic should be ignored,still the whole story is based on this plot so could not ignore it ...
