somehow mayank knows about nitya's plan that she married him for his money..thats how he falls for kavya's mum..
nitya asked for forgiveness and they reunite again and shlok is born whom mayank gave to vanshita..
he told nitya to adopt kavya but as mayank was still in love with kavya's mum nitya planned their accident and they both died..
so nitya raised kavya as her own son that to for a purpose as we all know and her son is raised by vanshita who happens to give birth to jai..
now about vayu well nitya was married to a guy called aman and after the birth of vayu left them both for mayank...
now shaurya too will be related to the nanda's as he will happen to be the bro of arav the guy whom kavya met the day of his death...these people r related to bauji how come...thats the secret?
