I think NK's role isnt still over.
I mean think about. They wont just rope in another person just to make Arnav a bit jealous for a few weeks😳
There's a probability that he's gonna be the angel of the show!😊
-The camcorder he's been carrying around might have accidently recorded something tht the whole family should hav seen like Shyam🤢 removing the brakes of Anjali's car (Though it may take the Raizada's a long time to see tht tape)👏
-Or he can become Khushi's friend 😃and try to prove her innocence b/w Arnav and Khushi, because at this point in time, no one is on her side!
