Confused about the characters

Hi Everyone,

I was confused in terms of who Payal from Kyunki is in this show. And also, is Maya, Mahen's sister? And is Shiv Mahen's only son?

Thank you so much

It is not clear whether Shiv is the only son of Mahen, according to the website, Rudra is also his son.

As for Maya, she is the only sister of Mahen and lives with her parents, as her husband is a "gharjamai"

I am not sure what role does Payal play, but most likely she is the sister-in-law of Mahen
