I just felt odd because it's quite clear that nanu and nobody other than meenu and parul knows this truth. Nanu only knows that abir's father abandoned them, other than that he has no real idea why.
Exactly!! Kunal's Dad is definitely not good because why else would Meanu adopt him and give him her name.
Seems Parul was in a fix and Meanu/Nanu helped her.
I might be in the minority, but I don't think Abir/Kunal have the same Dad!!
