Context : 1 subordinate of a general (Kubou sama is JP general /shogunate i think ?) said this to her after go into an open hot spring outside.
What does she mean by this ? My guess is "Really,you don't even care about your speaking tone as a general which is not supposed to be spoken out loud" Is she not supposed to be speaking loud or exposed her voice to public ? If my understanding is wrong please correct me thanks
