At Long Last perhaps

First they let it come to their mind.

Then they let it out in soliloquies.

Then they talk to their clothes about it like Ishita told Raman's shirt.

Sometimes they say it to the mirror.

Sometimes they mumble it to themselves and to sleeping beauties like when Raman says it while she sleeps.

Then at last they come to the point of saying it .

And he says kya and she can't look at him and he can't take his gaze off her and there they stand waiting for it to happen. And hey presto Mani the magician comes and almost with the swish of his wand rather words whisks the moment away and Ishita too.

Then we see that more than once in a way she discuses it with Mani, almost academically working out how to say it,- discovers she is not a poetess -- etc.

Then the numerous times they come close to saying it but are far apart.

Then they are physically close but haven't practiced their part.

Then when all is set the cvs send Mani,,Ruhi,the Bhallas, Commotion personified,,Mihir and a host of well meaning people and convincing situations to disturb them just then.

Now finally at the international airport its going to happen.There will be a chase, ,a human ring will form round them so they cannot escape and full facility will be set up to facilitate the escape of those three magic words
