Joking aside, you're reading too much into what I wrote. Never said this was a sure hint as some romantic developpement, just that I found interesting (and funny), that in the first chapter, she was all "you're cold, don't touch me", then in a later chapter she wouldn't let go of her hand, making a nice contrast in her attitude. I'm not expecting them to get all lovey dovey anytime soon, though that would be nice. And don't even think it was really intentional on the author's part.
