Kumud gets married to some else??

no he never marries to Kusum ... I have read wiki of both novel and movie ... he refuses to do it

infact after marriage when they meet kumud was ready to leave her hubby to marry saras but then she gets to know that her hubby died and then she refuses to get married to saras as that time there used to be no remarriages for widows ( novel ends here ) ... but now days they can't show it so hopefully Saras -kumud will get married 😛

frm movie wiki

When Saraswati reluctantly tells her, he faces a new Kumud, who must now embrace the widow's status. How can she hope to marry her old lover? Widows remain widows; they cannot give again what they have given once. She drifts away from him, again, led by her new duty. The only thing left is for her to convince Saraswati to marry her sister Kusum, so that she might be close to him, be "his companion". But he refuses. He prefers to wander away once again, and walks down the mountain, fleeing her. She follows him, singing that love cannot be life's only task, that others await one's devotion, that you must sometimes sacrifice love in order to fulfil your destiny. The film ends with Saraswati accepting Kumud's desire, and so sacrificing his will and hopes to devote himself to community tasks.

in the Novel Guman does not have that big role ... whatever the role she has is after Saras returns to the house after meeting /falling in love with kumud but here Guman is already in the same city to create problems
