No this is not related to Kayamath...
But Amit plays Hiten's son in Kyunki Saas Bhi Kabhi Bahu Thi....
He's actually Karan[Hiten] and Tanya's[Rakshanda Khan] son...But now that Tanya is out of Kyunki you can call him Karan and Nandini's[Gauri] son..Moreover Karan and Nandini are married in Kyunki...
Hope it helps..
