Yeah, if I were to write a fanfiction at this point, it would be about how Yuzu and Mei break up, that's pretty much where the story is. Mei doesn't really seem comfortable with any of this, like she's sure she made a mistake and isn't comfortable with having ruined her arranged marriage. To her, being a lesbian was just a fashionable fad that broke off from her taunting of Yuzu. Mei isn't gay, y'all, but Yuzu is.
I can see Mei finally getting the bravery to confront Yuzu and explain that she's actually straight and not into this but she's sorry about leaving their relationship so suddenly and then letting her down easy.
That's honestly the canonical headspace of this manga right now. I'd like to see Harumin admit she's a lesbian though. And then the confusion that Yuzu being single and out-gay causes for Matsuri. That would be spicy.
Then we could get a love triangle and Mei's straight adventures as a typical Japanese arranged housewife while Yuzu goes through the new gay lifestyle and gets torn between Matsuri and Harumin (who both have heavy sexual/emotional yearning for Yuzu).
I think that would be a lot healthier than what transpired at the end of OG Citrus and make new Citrus a lot more exciting. Mei was always the author's 'crush from afar'. The way the author is writing her makes me think she's guilty having projected her as gay. So make her straight, break them up at last, and let's get a love triangle going.
Harumin is by far the most interesting character left, but her and Matsuri and Yuzu could make a really nice gay burrito. Mei's not into any of this, it turns out.
Maybe Yuzu's mom could get a date as well?
Without interviews I don't know what the author is thinking, but Mei's regression isn't natural at all.
I can't tell if you're being serious or joking here...
