It is kinda... weird? That there's never a moment where Toudo actually confronts and admits her own not-straightness, the story just kinda skips over that to a version of her that acts as if she's always known she's gay?
It honestly doesn't seem to come up at all once the joke with the male teacher is finally put to bed, it's like we skipped an entire character arc chunk, or at least One chapter actually addressing it.
The story is still enjoyable in its own goofy way, it's just a weird blindspot, as if the creator had zero interest in anything other than the two polar extremes of her character.
