This is just my opinion based on body language, voice patterns, and overall vibe but COME ON! Look at Paras! He thinks he has won because he has new work starting immediately the next day. Its a pretty good attitude to have about moving on to the next chapter.
Comparatively, Sana kept sorta awkwardly justifying her place in the new show. Even before she was on the floor (when she presumably met her parents for the first time since signing), she was repeating throughout the finale that "Only if I meet someone I will think about marrying." Like, noone really takes these shows seriously and she herself seems aware of that and is trying to portray that even she isn't taking it too seriously either. She seemed super stressed out during the entire finale (even after elimination) and just seemed desperate to switch topics everytime the shadi show came up. Paras on the other hand, provided a perfect contrast.
I was very much on the "Sana is an adult fully capable of making her own decisions and her parents should shut up about it" side of the argument, but for some reason I feel like they may have kinda coerced her into signing it. Maybe it was a money thing, or maybe they just pressured her into signing without giving her too much time to think. Before she realized it, promo-shromo shoot hogaye, finale bhi agaya, and she is just like wtf did I do. Anyone else got those feelings?
