I've mentioned in my review for volume 1 how i hate that it started with heterosexuality being described as "normal", and how the protagonist, Uno-san, continues to feel disgusted by this new type of love she begins to feel for a woman.
As you continue to read, you realize though, that she isn't homophobic but simply in some kind of depression. She doesn't like herself and doesn't think she could ever be loved. She dresses up for men and wants to be loved, but as soon as they confess, she ends up rejecting them, because she doesn't feel the same and lowkey feels disgusted by the possibility of romance and everything that comes with.
So it ain't homophobia, which I'm glad, although the writer could have phrased it better at the beginning. I wonder how many queer readers have dropped the manga, just because the first pages seemed homophobic... I mean, I almost did.

Also, Uno-san more and more feels like she's asexual or somewhere on the ace-spectrum. (E.g.: she was thinking of kissing someone or what it would be like, and she felt disgusted by it. Also: she mentioned that she would want to be with someone forever, but without kissing and everything... so she wondered what that type of love could be described as.)
I kinda doubt the author will include asexuality, but I really hope Uno-san turns out to be ace. That of course won't change whether or not the two women come together; aces can still have romantic relationships.
