Yesterday's opening scene somewhere shows the dynamics of Maurya family.
Whether its shyamlal's naivety or foolishness, who is oblivious of world's way, thanks to this nature he didn't able to handle the business, hence got the tag of "failure".
Whether its Deepu, whos outburst over shyamlal was right somewhere. Due to Shyamlal's inability to handle money or business, family has to suffer. This may be the reason Deepu is like this-opportunistic, street smart, practical, little bit selfish as he know this is the only way to survive in today's times.
The anger of kanak over Deepu despite knowing that this time its Shyamlal's mistake reflect her dismay with deepu, that he never helps and choose himself over the family.
I think manu is amalgamation of all the maurya's.
