IMO other than Sid, Asim had a good binding/ friendship with Vishal, which I would rate higher than SidSim n he also had good friendship with Rashmi, but BB chose to show his friendship with shefali of all people.
He was never close to shefali n even when Himanshi was there he clearly told her that he didn't trust shefali ( which later he was proved right). So Asim's bonding with shefali was more due to Himanshi. Don't know what BB is trying to show.
Also he had some good bonding moments with Paras, Mahira, Sana n art other than Abu. Hope these finds too r shown in his journey.
