That is not true. Japanese people aren't inside a bubble. There's a lot of people fighting since the early 2000s in Japan, against the sexual portray of minos on media like manga. The age of consent applies to minors with other minos, not adult with minor.
There's no such a thing as westerns pushing their morals to poor Japanese people, we pretty much agree with the dangers that this comic culture bring to society.
I'm not even noth american, and westerns also mention my country in LATAM as "another world that westerns wouldn't understand with their morals of consent" and that is bulshit

Legit a good premise but its the same way on how I feel with Euphoria, why the nines are they highschoolers?! Evwhen I was in high school Ive always questioned that and honestly loved older romances and if you wanted to include family with logical privacy but in there life college. I finished it but In honestly disappointed because its a 2019 Manga I kinda thought we went past this. Also really didn't need to make him a minor its also the fact they clearly ironically enough different way how the dragon was a clear adult and time and time again explained the Mc was a minor. Everyone was okay with it in the Manga it was really hard to see it all as cute and even more disappointed the comments are on the same boat. It wasn't a bad Manga its just honestly could have the Mc in college and.it would had been perfect. What with people being okay putting children in adult situations when you can milk far more out simply using adults.
