Americans in general have a weird avoidance about talking about breasts casually. So for Mumei, in her mind, if she were to straight up say anything about Noel’s chest, just bringing the topic up would feel weird and creepy to her. Even though people in other countries like Japan would have no hangups about it at all.
@@user-py7um4gj7g To be more exact, It' common just among Japanese OTAKU to bring up such topics without hesitation, but not among general Japanese people. As evidence, や太郎 is completely unaware of that matter and saying things that are completely off the mark. In the US or many other contries, however, it's impolite to comment on someone's physical features like that.
