I found out what I think is a little off with this.
As much as it portrays various realistic LGBT situations, all the people involved are like ideals.
The lesbian couple is gorgeous, Misora is cute as a button, whether as a boy or as a girl, Touma and Tasuku are handsome, the transgender man looks like a handsome man, Anonymous is bewitchingly ambiguous, even the older gay couple looks nice.
As if average (or even ugly) looking LGBT people don't exist. Lesbians are all lipstick lesbians. LGBT people are all nice people who'd never hurt anyone, cross-dressers are perfect looking and puberty has no effect yet. This manga painfully tries to portray LGBT (or every variation of it) as beautiful, inside and outside, people, nice, caring, struggling within an hostile society, but becoming better for it, etc, etc...
That's cool and all, but pretty unrealistic. Gays and lesbians can be nasty, unhinged, manipulative, cheating, average, butch, imperfect. Like everyone else.
This manga idealizes us a bit, so I actually can't take it really seriously because it doesn't match reality that much. And I find it counter productive at some point. It's cool to be supportive and sensitive, but come on: lesbian bitches and nasty gays exist. We are people too, not gods.
couple years late but this isn't really true at all? Tasuku starts in a very bad place, and repeatedly lashes out at people around him, and Touma has a shit ton of internalized homophobia that causes him to also lash out and repeatedly hurt the people around him even more than Tasuku.
One of the defining character moments for both Tasuku and Misora is that night at the festival when Tasuku says Misora got groped because he was cute, and then Misora went off on a tirade about how disgusting and gay Tasuku is. Neither is blameless in the situation but nothing about that says "perfect ideal" to me.
Haru is extroverted and outgoing, but she also hurts Saki by outting her to people without thinking about the consequences of her actions. In the story it turns out okay, but Haru outting Saki to Touma's dad, and then Touma's dad outting Saki to her own father could have gone really badly.
Anonymous has successfully dedicated their life to living as best they can outside of the confines of labels (and society) but this can also make them aloof. When Tasuku ends up opening up to them, he ends up feeling more lost than he did before talking to them.
Tchaiko is held back by his own fears and insecurities from meeting his husband's son, and almost lets his fear of confronting his husband's other family stop him from being by his side when he's on his deathbed (lots of he/him pronouns wow).
point is, these are all people. They cry, they make mistakes, and they're all trying to do their best in their own ways. I never felt like they were too perfect, except for the magical realism parts where anonymous walks on clouds but I'm pretty sure that's the intended feeling.
