Santhi, baat honeymoon ki nahin, baat as you have pointed out, Inke cold cold relationship ki haiIf you notice in any scene, Danny and kusum are physically very comfortable with each otherWhereas Saras and Kumud have a huge no entry zone between them, in most scenesThat makes their scenes together look very artificial and contrived. They need to portray closeness,by sitting closer, using softer intimate tone of voice, touching each other more - I don't mean romantic scenes, they can be discussing Guman, Danny, kusum or whatever, just in a way two people who are really close to each other do, by entering into each other's personal space.
