I love this manga, it's very cute and the thought of antis hating on the two of them makes me furious, but... If this happened IRL I would 100% be thinking that it's a tax evasion scheme ngl. It's some real yuri manga bs, but we accept it cause it's adorable. I mean, pretty much nothing would change if the story was just 'Ruriko is secretly in love with her roommate, Kurumi' (though I'm aware that, apparently, roommate arrangements aren't really a thing in Japan).
Anyway, cute chapter and thanks for the translation, as always.
