I honestly think this is pretty interesting writing. The first six chapters never show Hana's perspective, which builds her up as a mysterious, confident antagonist. The first time we do actually get to see her inner thoughts, she's confused and clearly misread the situation, which just makes her pathetic and immature instead. It feels very true to how real people seem like they're in control at first but are really just messed up inside

It's such a trip to watch someone on this forum get upset on behalf of a husband character because his wife will supposedly leave him or cheat on him in a later chapter. I wonder if it's a first. Ohsawa Yayoi might be breaking new ground in ways she doesn't even know.

I'll be incredibly bored if Harutaka ends up doing an unsympathetic heel turn as an excuse to justify the girls getting together. I want to feel terrible about his undeserved suffering

The About Names part is about a nonbinary person, right? Not sure I've seen a lot of that from Japan.

I think Japan tends to prefer the X-gender umbrella term. I also get the vague feeling that they feel like labels are kind of constraining in general though
