As actors, they bring out the best in each other. Both are giving very natural performances. But I think half the credit goes to the dialogue writer. The dialogues between the two are very smooth flowing and seem extremely natural. Ayaan's way of speaking is extremely funny. I like Ayaan and munteha are very aware their own flaws. She knows she has a problem of being too submissive and he knows he is insecure.
The story is really cliched but I have rarely seen such self aware characters with killer chemistry to boot. Hope they don't screw it up in the upcoming episodes.
