i dont think the rumours are reliable!!!
also why in the world would CVs destroy their own show with such garbage plot!!!!
the only reason why we are putting up with the idea that khushi and arnav will be engaged to the other - shyam and la is because we know that in the end, arnav and khushi will be a couple though we dont know the situation.
CVs are very good in showing the symbolic meaning of things. so far all the symbolism point to arnav and khushi being soulmates / couple etc. so what's the use of doing all that for khushi and arnav to lend up with someone else. totally makes no sense.
dont forget this is the same production team that created geet. once a couple is kind of suggested (the main leads), they do a good job in maintaining the attraction between the two as the difficult situations arise. they dont usually destroy the idea of them potentially coming together. they might drag it a bit but not cut the possibility of arnav and khushi marrying so early in the show.
also why would shyam divorce anjali since he has already stated to shashi that he wants both women: one for the money and the other to fulfill his lust!
