I don't share the anxieties of that other poster, but... You might want to read what you wrote back to yourself because it actually sounds pretty similar to the conservative weebs that whine about same-sex shipping. Like, you are just scolding someone for enjoying the lesbian themes of this series and hoping that some of the girls will form couples with each other.
"The main point of this series is to think of it in terms of a yuri school campus story", said the mangaka in the vol. 3 afterword. Would you call them an obsessed fetishist too?
I'm not scolding them for enjoying the lesbian themes or yuri shipping, I'm scolding them for obsessing over tags instead of actual content of the manga we're all reading right now. Just like people don't get to demand that authors don't put some gay characters or couples in stories that aren't labeled yuri or yaoi, or shouldn't bitch about people who are gay-shipping some characters, people who read stories with gay or queer themes don't get some protection from author writing in hetero stuff or even not-gay ending. It's just a question of how well it is executed.
And since this manga obviously very gay themed, with main character's backstory being mostly about betrayal of her gay lover, with all the gay symbolism there is, why start discussing some completely different manga with gay characters that happens to just share the same tags on pirate website? It feels like treating the story as suspect just because (very few) named male characters actually exist in this story, unlike some other yuri stories. I dislike conservative weebs bitching about gay shipping, but I also dislike (rarer, I admit) folks going "why there are males in my yuri manga?". Or also people going "why is there romance in my shonen action manga?". Generally I feel people who want their manga to conform to their favorite little boxes, like collection of few tags, and are mostly concerned about that conformance, are disrespectful to the authors. Everyone can simply read the manga itself, it's clearly not about MC's romance with some random guy, so why insist it's becoming more likely? But it can also end up as tragic doomed yuri romance, and it's author's right to write them never ending up together.
