I'm still rather dumbfounded (although at this point I shouldn't be) that apparently the writer wants us to sympathize with Liz's dilemma of being torn between Maki and her ex, and to see Liz's popularity being OK with the lesbian revelation as being a good thing.
And loath as I am to speculate about that stupid cliffhanger, it seems likely that Sumire has some sort of revelation that will break Liz's heart and send her back to Maki.
Rarely have I read or seen any work of art where I had such a clear sense of what the creator wanted me to think and feel about the fictional characters and events while I absolutely did not think or feel that in any way, shape, or form.
What's crazier even still is that Liz is pretty clearly a self-insert for Kitta Izumi. This whole thing is basically her saying "Yes, I'm a selfish asshole, and yes, I have issues that will bite you in the ass if you get close to me, but you MUST cheer for me because I am a HEROINE breaking barriers for lesbians EVERYWHERE. Or, at least, I fantasize about being one, which is JUST AS NOBLE, and therefore I deserve a doormat-chan to walk all over."
Yes, this is the most absurd thing about it: Liz is the most blatant self-insert I've ever seen (even before her name reveal...) and it's also an incredibly unlikable character. It's kinda funny, I don't think that's what Kitta Izumi is trying to convey, but it's very hard to like Liz. Sumire is unironically a good character because she's supposed to be a manipulative asshole and that's what she is. Maki is too passive for a MC, Liz might be a victim of manipulation but in the last few chapters she comes off as having forgotten about her girlfriend.
