I’m going off the first seven novels (I haven’t read the eighth yet and the others aren’t translated and/or released yet), which you might want to read for the rest of the story since I’m pretty sure the anime will never get another season let alone the 4-5 seasons it would take to finish it without huge cuts. The prose isn’t great, whether that’s a translation issue or a problem with the original text, but it’s not terrible either.

I think Momo is the only character who remains 100% unambiguously gay, while Menou continues being kind of ace and who’s baffled by the attention she gets and never displays any sort of attraction towards anyone, and Akari is kind of inscrutable even to her own inner monologue for plot reasons. Even after all the spoiler stuff happens they’re still textually “very good friends.” There’s a reason I’m calling it absurd and egregious: Menou and Akari so obviously have a romantic relationship and are literally soulmates that when we see their internal monologues where they textually don’t see it that way it’s jarring to the point that it seems like parody.
