- Not enough works depicting the potential and actual consequences of being gay.
Sorry, but what do you mean by it exactly? I think we got plenty of stories depicting homophobia and characters being bullied/dealing with prejudice over it?
imo this is an issue that partially arises from the typical setting (highschool, so consequences necessarily must be somewhat limited) and the author's usage of the (usually male) antagonist/villain-style of homophobia; effectively, you got someone in the story (perhaps a tyrannical father, or an asshole ex-/would-be boyfriend) and they must overcome/"defeat" them and then once that happens it's at least implied everything's fine now.
But that's not the same as a portrayal of pervasive homophobia; that's not "over" once you've "got your girl", you can't just "defeat" some homophobe and then you're good for the rest of your life. And I would say that manga ... I'd almost say never go into the nitty-gritty of what that truly means - especially in Japanese society, especially if we also talk about sexism and whatnot on top. For example, in work, and socializing around work, and career. Or in renting or buying property, or sharing medical costs, or having say in medical decisions of your partner. Or the political atmosphere within the country, perhaps things like small town communities vs big cities; different generations of Japanese, who knows. Anything of that sort.
It's really only "this guy is in the way and now they aren't so great! Yay!" Maybe there's some joke about getting married abroad. And that's fine of course and it can also be fine to have stories where everything's always great but I would agree that some more real nitty-gritty manga would be interesting. Something like Ikoku Nikki but (more) gay, and at least as my memory goes there's nothing (and also, because that might be suspected, Ikoku Nikki isn't bleak. This wouldn't have to be a bleak story either. Just a different one).
