Uh... I wonder what "Age of Consent" part you don't understand... Age of Consent... Mean if the person doesn't refuse or disapprove meant it's fair and square, if it's forced then that's different story, also, why do you think a lot of japanese around highschool can go on dating sites and date older people? That's because the consent of japanese law is so low.
If you don't agree or disgusted by it then just don't read R18 manga, stay clear of Yaoi, Yuri or Mature genre, stay clear of it.

Honestly the whole minor thing goes by case to me... because I ain't gonna lie to myself and pretend 16+yo is very interested in xxx and romance. Sure, some don't but many are. And I also won't lie to myself that girls that age are more interested in 20+yo guys than other teens. Same with some boys. I think there's a big difference in being attracted to someone older and being groomed to like someone older... as well as liking someone 17yo and liking someone because they are 17yo.
Honestly I think that such a big worry over his age reflects how much teens are purposely target in the society the person lives. And there's also American media... teh either have teens acting like kids or adults pretending to me teens... it's basically... dsney chanel or euphoria... there's hardly a middle ground... and in the later case, because we know it's adult actors we don't consider it as much teens but more young adults.
But that's just me... and I mean... I was the kind to go after college guys... or don't even ask about age as long as I was attracted enough... and still remember a couple classmates that went as far as go after a young teacher so... yeah... as long as it's not grooming or too pedo I'm ok.
Personally I'm more concerned about adults in the bodies of kids "falling" for kids and the whole fauxcest route (adopted/step sibling turned love interest) that I see a whole fricking lot on romance. My second concern is sh and sa being romancized and normalized in adult comics technically targeted to women... and theres some yaoi out there that is even harder to read than those... this one is super cute and lovely compared to those. ╮( ̄▽ ̄)╭
Sorry about the essay... xD

Yeh but most girls have that?? I was the exact same way as a teenager going for older guys but now as an adult thats so fucked up. I realise how much of a power imbalance there is and that inherently makes the relationship problematic and manipulative. I have never met a girl who dated an adult as a teenager who had a good experience myself included cause these guys who will date a 16 year old clearly realise that these girls are young and naive, they understand women their age will not fall for their tactics so go for younger girls whether or not its unconscious or consciously.
Honestly now I could never even date someone whos 18 let alone someone whos 16, the thought of that makes me sick cause they're literally babies ):
No one gonna question that the red head is a minor?!
