Mihir Virani - the most important character in the Virani Industries... and Tulsi Virani - Shantiniketan's Pillar...
The "adhar" and "chaalk" of Virani industries is shown to be the greatest benafactor to the company. He is potrayed as a person, in who's absense nothing can happen, or when he is not around something in business has to Go wrong...
In the same way, when Tulsi is absent from home, there have to be fights, or something "ashubh".
Tulsi solves all the problems, and has transformed from a "pundit's daughter" to a lady who fights for truth and justice....
Tulsi and Mihir have also been potrayed as the ideal couple. They have been given the post of being the two people above all. Savita, Gautam, Sahil, Ganga, Karan, Nandini, Prajakta, Hemant, Pooja, Kesar all bank up on these two characters who support and propogate the progress of the story and Kyunki, and though the story revolves around Shantiniketan, the people mainly responsible in the formation are Mihir and Tulsi....
