Something like Reverse Thinking/Walk in my shoes?

i heard "sadistic beauty bl side story" has a toxic vibe.
if you want good psychological toxic mutually obsessed crazy codependent morally gray bl with characters that were nice in the start but it's the fucked up life that made them be painted in bad way then i recommend"unchanged man"/yuwon everlasting. it's my fav BLs rn. BL so good you lwk hate it when the new chapter is abt smut rather than story T_T. JAKPIL THE GOAT!! please read it's so good. it's got no size difference, no age gap, virgin x virgin trope as well, so u know the obsession is insane level.
