I have some feedback, too 😀 Let me start by saying that I like your art style, even though I generally despise mangas. It's nice speed painting and it has soul. A couple of times I've seen odd body proportions, but oh well, anatomy is tough.
As for the writing, I didn't get that horns represented same-sex relationships - but it could be because all manga characters look like asexual minions to me, so I couldn't identify which sex belonged either one of your characters. I simply thought they were doing something considered wrong by society, but I couldn't connect that to homosexuality. Given that I'm a lesbian and I didn't get it... You may wish to talk to other lesbians or gay guys to confirm. But then again, do keep in mind that I have extreme difficulties understanding any manga character's sex, so it could be just me 😂😂😂
At any rate, because I couldn't make the connection, I was left with a sense of puzzlement. I understand that the blossoming meant acceptance of themselves, though.
All in all, I could follow your story more or less easily, but I couldn't fully enjoy it because the most important detail was lost on me. Maybe making that more explicit would help.
I hope it helps!
