Suhani will end up with Hate-Love for Yuv and will be gone!
I think, If Yuv doesn't do anything about his feelings of love NOW -
Su will take time but come to terms that her bff ms.snakina. is best for Yu and move to her dad's (if she's true to her nature).
Whether or not Yu loves Somu now will not even be a matter of concern, as snake-babes can project it the way she wants. Being a woman, Suhani will buy her friends' version
Reason 1: It will be quite difficult for any normal girl to imagine that a friend is a super-snake and can calculatedly do stuff to make different people see different things by applying colors to a single incident..Snake-som seems to scale new heights in this dept.
Reason 2: Suhani will assume that Yuv was always in control of himself and never physically expressed love as he always loved 'Somu' even while being room-mates with her. Su will reason that Yu is 'thanda' with her as he loves Somu! Yuv never technically was a husband and on top never once spoke of his love/feelings for SU anywhere, leave alone to SU!
Assuming Suhani's gonna go from BirlaHouse-
which i think she should btw-at least it will wake up slumber-jack Yu and make Suhani independant and less-naive):
I think if the CVs eventually want Suhani to come back to Yuv, they will have to show a Yuv that is more expressive about his love in words and actions NOW.
Else, reason #1 applies and she'd plain move on *end of story*
