There’s Prem’s lover/wife

And he has a mean step brother, Neil Nitin Mukesh whose true intentions are on full display in the trailer itself

Everything is great in their paradise until...

There’s Prem’s humshakal who takes over their lives

But we’re certain that there will be a happy ending and it will have a message – It’s all about loving your family. Hum Saath Saath Hai…

And then Prem’s ladylove finds that there’s something amiss in Prem’s behaviour. She even mouths a dialogue in the promo, “Kabhi kabhi aisa lagtaa hai ki tum koi aur ho"
