i think what the op is referring to is when yuuto's woman friend mentions cheating on her husband as a joke. casually being able to joke about something as serious as cheating implies to me that maybe she's already cheated on him before, which feels like such an unnecessary addition to this story?? we didn't need all that and it could've just been a totally normal hangout but the mangaka adding all that for no reason feels a little misogynistic?? idk if this makes sense. not sure about the racism comment tho since i haven't read this mangaka's other works
THANK YOU SO MUCH
YESSSS
There is some minor detail like that in every single one of their works that seems insignificant and adds absolutely nothing to the story but is still there for some reason, and it just feels misogynistic
The racism is in an extra of another work tho I don't remember which one per se since it's been a while and I read a lot
I hate rereading stuff so I couldn't go back and reread every single work just to convince people. If they didn't wanna see it, there was nothing I could do about it

This author knows how to write a good story but somehow ALWAYS find ways to add a very small unnecessary part in the story to show their misogyny or racism
