Hwang young's misery (I think it's perfect for you. It's a BL spinoff of Stephen King's Misery (no rape x sa ofc) where this webtoon artists gets kidnapped by his fan and forced to act as the characters from his webtoon. Eventually he crosses this line of whats real and whats fake and it also touches on how the guy became like that and why the mc fell for the guy despite him breaking his ankles and confining him. It's so underrated, It does not get enough attention istg)
* no rape no sa
A cozy obsession

( You'll love this , they both matches each other freak )
not really toxic, it's just a better descriptor for what i'm looking for cause it's unconventional. i'm looking for bl where they're mutually obsessive about each other, unhealthily.
example is llewellyn's candlelit dinner. spoilers: the MC said he'd break the ML's ankles so he wouldn't leave him, the ML's also a bit of a nuthead himself.
i'm not averse to smut. i prefer the guys having similar builds, but i'm also not averse to the stereotypical yaoi builds. no r*pe, SA or dubcon.
i don't think this stuff is good morally, FYI, i find it an interesting relationship to explore.
