While I appreciate that translators are willing to work hard on manga that might not fit the audience where they're posting, and this translator's work is amazing, I can understand why this isn't exactly popular here.
The most obvious reason is that it's not yuri as other people have mentioned. The tag system makes it easy to identify things that people might not want to read so that's fair, but posting a het manga on a site that predominantly deals with yuri isn't going to get you a lot of views and comments. I'm one of the people that likes to explore different genres but I come here specifically to read yuri. I'm not opposed to it being here because I think it's great that Dynasty is branching out, but I'm still hesitant as there are plenty of other places that host het manga. And plenty of het manga too.
I personally feel like this manga fits on this site because it's more so about the artistic appreciation of the feminine form rather than having a focus on heterosexuality. There likely will be romantic elements in the future, but that doesn't seem to be the main theme of this story as of yet, so I wouldn't write it off as just being some het romance thing and nothing more than that. The story is as much, if not more so about women, than it is about Haro.
The second reason might just be my personal opinion but the main character is uncomfortably pushy about their desire to 'paint beauty' and believing that everyone should be comfortable viewing or being nude. And he specifically targets women.
Because he finds women beautiful. He's not out here tying women down and forcing people to do things against their will. I very likely wouldn't be here reading this if that were the case.
Some individuals in here romanticize his behavior as being dedicated and pure, but the reality is that he ignores boundaries, harasses people, and expect others to have his same values. He makes people uncomfortable with topics that are s*xually explicit (in society, not necessarily in art. Or even in his art). He might not view it that way but others do. And he doesn't care how uncomfortable he makes people with it. This is played off for comedic effect sometimes here (and often in other manga) which bothers me a lot too. Romanticizing this behavior, like the manga and some comments do, encourages the idea that we should be accepting of everything everyone else does no matter how uncomfortable that makes us.
This feels like you're projecting your own discomfort onto the characters, here. That's the thing about tags, if a guy's aesthetic attraction to women is making you feel uncomfortable, you don't have to force yourself to engage with it.
Plus in the real world that 'purity' that's exhibited by this character is so uncommon that I'd be surprised to meet someone like this who doesn't have ulterior motives.
I don't understand the purpose of this point, other than to be presumptuous of hypothetical strangers' intentions. Even if this were true, though, and people are primarily motivated by sexual attraction, why is that bad? Feeling various kinds of attraction isn't bad, or shameful, or degrading in and of itself, it's what people do with their attraction to other people that counts the most. Are they still respectful of that person, or no? Do they respect boundaries and people telling them "no?" That's what counts. Slip ups are fine too, so long as no lasting damage occurred and people (or fictional characters in this case are shown to) learn to do better.
As much as I love art and beauty, and beautiful women and men in art, consent is an important factor in this type of endeavor. The main character has trouble with consent a lot. As many manga protagonists of his nature do.
I've never seen Haro not take no for an answer nor force anything onto anyone thus far. Maybe I'm forgetting a specific instance though, so feel free to let us know which chapter(s) this happens in. Over all though, it feels like this critique stems more from a bias towards perceived cis male sexuality. There are more objectively egregious manga series on this site, and the rationale that it's all okay because it's fiction and fiction is a safe home to explore taboo without causing harm to real people is solid and one I personally subscribe to, but this should be extended to non-yuri manga as well.
Any manga that genuinely appreciates the feminine form should have the potential to be welcomed on this site. Tags exist, so people can avoid them if they're strictly here for yuri, but as a sapphic woman that enjoys the feminine form in much the same way as Haro does (though I'm not exactly an artist), I greatly appreciate this series being here. I likely wouldn't have come across it otherwise, since this site is my main haunt for manga these days.
