Pranav Gupta's answer is actually WRONG. Ranga was not Shyama's son. He was the village accountant's son(Shyama was not the village accountant)
Ranga is the son of the village accountant who has been to bangalore to persue his higher studies. In those days, this was not a normal thing. He was a very humble and down-to-earth man. His ideas about marriage was initially changed when he came back to the village, but because of his love with Ratna he again changed his mindset.
ratna was a sweet girland she was eleven years old. she was from a big city. she knew how to play veena and harmonium.she sang very sweetly .she was beautiful and had innocence on her face. she was quite sensitive to the surroundings as whwn stranger ranga came she stopped singing and when the writer and ranga talked about her she went inside.
