Saraswatichandra is a man with firm and determined personality. Saras is a person who strongly believes in his religion and spirituality. He not only loves his deceased mother but also follows her teachings dearly. That denotes how his love is. His love is undeniable and with absolute devotion. He is raised by a strict father and a step mother, who fakes to love him but still he remains clam. He respects his parents and strictly stays on his promise even if he didn't want to.
Whereas, Kumud is a spirited person, who has her own mind. She just doesn't follow anyone else's decision not even her father, whom she loves the most. She makes her own decision with her own knowledge and mind. She is the person believing in fairy tales and destiny yet staying firmly on ground. Her confidence and courage in irrefutable.
Just like Saras's father said, Saras is calm like a moon whereas Kumud is fierce like Sun, both having their own nature. Indeed they are made for each as both sun and moon are necessary for existence of world.
