i also think Sid gave enough indirect hints about him being together with shehnaaz post BB . i list out 10 of those things -
1 . Sid 1st post on insta post BB was a pic of him with shehnaaz which is a very big thing . 1

2 . Doing 1st mv with shenaaz , he himself finalized the entire thing as shehnaaz was in msk .
3 . Sid gave many of his tshirts to shehnaaz and not stopped her to wear during Msk .
4 . Shehnaaz wearing Sid’s mom dress , and it was not done without consent of Sid . 2

5 . In the intial days of endorsing of products , they both did endorsement of same products .
6 . When shehnaaz father was facing some issue , sid liked a sidnaaz mv which was not any V, , but a very romantic vm conveying that he was solidly behind shehnaaz . 3

7 . By the end of BB , Sid was friend was pahira and rest all the contestant as well , but he only promoted Shehnaaz’ Gill's MV all SM platform .
8 . Sid did insta live with Shehnaaz and posted the video on youtube with cation as Our First Live together . 4

9 . Sid posted same gifts of fans which was posted by shehnaaz earlier .
10 . Sid kurkure adverisment with shehnaaz in which he told the last line – tedhi hain par meri hain , although it’s a tagline of kurkure , but still the way he told that line explained everything . 5

Even after all these things Solos still pretend to ignore and don't respect the feelings of their idol then there are doing biggest disservice to their idol . Have some empathy and do acknowledge the sentiments of your idol .
