MUMBAI: In the upcoming track of Star Plus' Yeh Rishta Kya Kehlata Hai, Kartik’s doubt on Naira intensifies.

So far, viewers have seen that Mihir’s increasing proximity to Naira has left Kartik feeling extremely jealous.

Other complicating circumstances have made Kartik suspect Naira and Mihir’s relationship.

Meanwhile, Kartik learns that Naira lied to the family about going to office. In fact, she is meeting Mihir in a cafe.
