While I don't like the way Pramad treats people in his family, especially his new princess bride, I LOVE the way Kumud's sisters worry about her. Sisters have that connection that is unlike other siblings because they know when they marry their days together will be less and the emptiness will be more.
And I love that they picked Kusum to go visit the princess rather than Kumari, not because I like Kums any less but Kusum is a little more mature so yeah she would be able to pick up what is going on faster. And she wouldn't have the fear of damadji to tell him off and defend her big sister.
Not to mention, Kusum needs more track. So far, she hasn't had anybody in her private life so we're still waiting for that. She's only been the cupid for Samud and there is more to her character that meets the eye.
