Here's Kaori's reaction when she thought that the Kodan Productions agent was trying to recruit Yoshioka to do porn in chapter 23:
What's happening at the moment with this manga is that it's becoming evident how bad the author's writing is. The author wants Kaori to get involved with AV, so she is writing in a very convenient way to make it happen. The author even introduced a character just to glamorize AV, Saori.
The thing is that since Kaori wants to be an idol, getting involved with AV is a big no no. If anyone finds out, it's an instant career ending. It doesn't make sense with what was presented of her character.
Recently
the author went on X to vent about the harsh comments she was receiving about the manga and blocked the comments. If the Japanese public is criticizing you, it really is a sign that you are doing something wrong.
