he wants kakun to say that she loves him front of the whole family...
gosh how can she?
1 she doesn't want rahul to know how she feels for him
2 she wants naina and rahul to get married
i think rahul will make her sing..
and in that song she would express in a sly way how she feels for him
but everyone would think shes singing for aman but rahul knows its for him.
