Its the human tendency that we only focus on the top premium level / only on winners, nobody care abt side actor or supportive staff. Munna Sharma is really the Unsung Hero of HD, while all the viewer's or fans just focus on Indira/Zaara/Rishi this guy do his own work and do exceptionally well each and every time. The way he acts, the way he gave dialogues are really very special. "Mrs, Mother, Tinde, Chote" that words dont know why feel so caring and loving and that accent was simply oustanding. This man always enjoys what he do and dat shows in his performances. Episode of 31st December 2012 is just an example of Munna's caring nature. Post leap period the bonding between RK and Munna is a treat to watch. Its not wrong to say that Apart from Indira and Rishi, Munna is also one of the main part of the show.
If next time you see Munna try to see through my point of view, just give it a try and you'll come to know how amazing he really is...
