"Sense & Sensibility" is Jane Austen's tale of two sisters, Elinor and Marianne Dashwood, whose father has died, leaving them and their mother to fend for themselves. The older sister, Elinor, takes on a leading role, and tries to shove her emotions down so she can help out her more emotional younger sister and keep her family from poverty.
There are definitely traces of this tale in the story of the Sharma family and its two sisters, Kate and Edwina (Charithra Chandran). Like Elinor, Kate tries to figure out the best path for her family in the wake of her father's death, and like the Dashwoods, they must rely on a family friend to provide them with a place to live.
There are also echoes of Austen's story of destitute sisters and their mother in the story of the Featheringtons.
