Girl realising she's on TV is all an assumption and even if for argument sake we take that, then too, if she's not comfortable now, for whatever reasons she has the right to voice it.
My take on this whole matter is that whether boy or girl, if it's mutual then it's fine, but at whatever point, who ever starts feeling uncomfortable and backs off, then the other person should respect and not try to encroach the personal space. Teja had been telling him indirectly to back off, but if he doesn't, then she needs to say it bluntly and directly.
And that also applies for all HMs. Seen many comments about teja doing the same to the guys, and if any of them r uncomfortable, they should be vocal about it n teja should respect that.
