Asim and Sana had a nice bond in start when they had SAAS group. I still do not know y that group broke. May be it was coz member were not sincere to each other except Sid and Sana and so they survived till end and afterwards.
because it was Sid who tried to keep them together . All three were with Sid but not with each other . Sana Asim liked each other till week two but after that I don’t know what happened between them, may be Paras successfully turned Sana against Asim .
Sana nominated Asim for Jail Paras ki baaton mein aake and I believe because of this Asim never trusted Sana again , he refused to give Flower to Sana during that rose task and gave it to Arti . Arti toh thi hi jealous , she acted like she is with Sana infront of Sid but she was never with her and Sana too was never fond of these two .
Then after Himanshi’s entry , Sana left Sid to join Paras and Sid was so heartbroken and Sana also realized her mistake and during this time with two new entries ( Himanshi and Zariwala ) and feedback about fanfollowing , Asim started thinking that he alone is so strong , has his own group now ( Asim , Himanshi , zariwala , bhau) and doesn’t need Sid anymore , iss time tak he learned the game from Sid , got to know his trigger points . So after using him for 5 weeks he ditched him and went against him .
Arti madam tried to patch them up because she was upset that Sid now has Sana and also Paras and Mahira but things became so bitter between Sid and Asim then Arti also had to choose her side .
