It's either a bdsm or the mc's a boring, flustered, incapable person? The female lead: cold faced, black haired, the rival: seductress, brightly colored hair... I wished they'd adapt more gl novels and give us more interesting dynamics instead of being stuck in the 2018 tropes,
SO TRUE, I love gls but it's so difficult finding an interesting one these days. Most people concentrate on adapting bls and that's sad, we need more gls with a REAL interesting and green flag plot, not that boring and sadistic/masochistic shit! (if you have any recommendations tell me, I'm desperated LOL)

I cant remember if its isekai or not but from what i remember the mc is the typical barons daughter (adopted, i dont wanna spoil but backstory is the baron adopted her and the mc was a child during this time the baron would rape her(?) Poor mc and the prince was attracted to her and it wa smention they did have sex and the mc was so happy go lucky with it like it was nothing and basically co frontation scene where prince annuls engagement with dukes daughter the fiancee to marry the baron daughter but the villainess is inlove witht he barons daighter and since barons daighte ris after riches she gleefully accepts it and its a slice of life chapters with lovey dovey moments lways ending in the villainess 'pampering' (sex scenes but not explicitly shown in manga) our mc and theres the villainesss nanny or old maid and pervert cat cute chubby perverted cat obsessed with yuri (watching thr lovey dovey moments between mc n female lead) its a nice sweet manga with dark undertones the longer you read it the more dark stuff is shown revealed about mcs backround basically her traumas
