The challenge was stupid and itv specific. It was unrealistic as well... Like how can you actually expect a company to sort out its first business of WEDDING in a month! If they would have made KT and Preeti do that, I would have been seriously disappointed.
I am glad that they sorted out that Preeti won't head to Tarun's place even after losing the challenge! It was needed... Things cannot always go according to Tarun's way (though I know nothing goes according to him..but still)
