Well, that's really an interesting theory! Who knows, this serial is famous for throwing up last minute surprises and minor shocks! 😆. So there is a possibility that Adi and Manisha knew each other, but love???? Don't know yaar. 😕 😕 As usual, I'm confused!
Or it could also be a one - sided love, i.e. Manisha liked Adi, but the womanizer that he was Adi probably wasn't serious and she was heartbroken and that is why she doesn't want to come back.
Right now, all we can do is speculate and keep watching IC!
