Rashmi definitely likes Umar and Umar likes her too, but I don't think he's the kind to go all out on national television (unlike Asim). In the initial episodes when Rash came he was more open like hugging her all the time etc. but since Devo started talking about them he backed off. I feel Umar is awkward and might not be as expressive when it comes to girls (he basically has no game lol) or maybe he just doesn't like PDA (also the fact that his family is watching - including his niece). I remember he told Himanshi to be careful as well when she went in again (which did not happen).
I am also still confused especially cause I feel they don't really talk about the outside world. Like today Rashmi had no clue what his specialty is. On the other hand the way he complimented her after she got dressed, trying to help her chop (even shamita noticed), acknowledging twice today that he likes her (and third time in the livefeed - not as a friend only), calling her "meri wali" etc make me feel he's into her but he's just awkward like that. He is also more in control of his emotions as we saw how he did not cry when Rajiv was evicted but we all know he's affected by it.
Let's see...I like both Umar and Rashmi so would be more than happy if they end up together.
