This isn't even Toxic, if anything it's just...sad? The most "toxic" thing you could say has happened was the kiss, but it led nowhere. I think people expecting super heavy drama from this story will be disappointed. Also anyone jumping to the conclusion that she's going into sex work is silly, read the url names on the page. The word 'Trad' brings up the image of someone acting like a traditional house wife. There's 0 reason to believe it's prostitution.
I'm way more interested in the character writing and political themes that continues to be woven in this story. The branding of this being some epic NTR story seemed like bait to pull in readers who wanted something juicy but instead got a slow burn story about Japans patriarchal society and how that affects women and lgbtq people. And I wonder ultimately what the "case/theory for same sex marriage" will mean at the end of the story.
