I honestly think Aya handled this chick a lot better than I would have. If I had heard the protag say something like that so loudly I would have gotten so irritated I'd have chewed her ass out. She clearly is the type who acts first and considers the consequences later - no matter how well she can read the room, she still tends to jump headfirst into situations and speaks her mind without thinking about who might hear it.
Aya...please, don't lose!
