I think in the piano rounds, audition rounds, partner rounds etc sony used charus image alot. I think this is alot to do with her looks and dress sense.. I mean they "used" her personality becuase she is a good looking girl and this meant alot of pple would tune into get a glimpse of her, which resulted in high trps... Now Iv noticed sony has another trick up their sleeve, they give Deepali alot of cover becoz she is popular within the group and also a good singer,so the attention is shifted to her . Charu is like in the background. Sometimes I even forget she is there.. What do use think.
Just my opinion no offence to anyone 😃
