ok now that we're on the same page and you provided an answer let me correct my initial questionBecause the male audience she is referring to is the JAPANESE male audience, one where gyarus aren't exactly the most popular kind of character (Why do you think gyarus almost disappeared entirely in the 2010s?), and one with the personality of Marin, 5 years ago when publication began, was certainly a difficult sell.
It's easy to see why she was worried, and was even expecting the axe because of it.
Situations like the one you mentioned (The "What are you looking at!?"), are popular tropes for a reason.
Mangakas keep adding them to their works because they're indeed popular with the general Japanese male audience, as annoying and tiring as we find them.
what the hell are japanese males smoking?!
