It's just the general atmosphere I felt in this work, not sufficiently explained in a single sentence. There are billions of women in this world, so of course there are all kinds around, so, no, I was not judging whether this is unrealistic or not. I was comparing this to other manga/manhwa in my mind, not to reality. She just acted like she didn't care about her gender at all, and was greatly amused when she noticed the male colleague suddenly became aware of her, whereas in all of their time together earlier he hadn't cared at all, which would have naturally been the situation if she had been a man previously. It was in connection to this atmosphere that when she talked about her breasts, it was like she was talking about some other person, which, again, would kind of have been the situation if she didn't really feel like her own body was truly hers.
