Anyone have recommendations that are like this and red mansion?

they only have it in novel form i believe, but the ZIG omegaverses have similar plots. Particularyc Lick me up if you can (Ashley x Koi)

Another one thats deeper in black is Ashley’s father, another prequel to LMUFYC is with Dominique X Ashley (Ashley is named after Ashley the mom) but that doesnt have a good ending, but still obsessive
