Well the show is apparently a true adaptation of the turkish show ask-i-memnu so you should maybe read it on wiki to know what to expect, because they are planning on sticking to the original, which I think will be good because it will be different from what has been presented on indian tv till date.
I wonder how they will represent the extra marital affair of the female lead though, because the indian audience are surprisingly so backwards that they have no problem seeing the male lead having an affair and cheating on his wife, yet when the role is reversed and they see the female lead doing the same, they start protesting and everything.
