I'm talking BL specifically bc that's where I notice it more. I notice many people 'simping' over these characters that have raped, threatened, beaten/assaulted, or otherwise harmed the MC (or even other people). I don't quite understand how they can do that- to see past the literal evil that the character is because they're 'attractive'. I don't think the excuse that 'it's just fiction' applies because fiction /does/ affect reality to some degree- and even if it doesn't what's so thrilling about reading some poor dude get assaulted until he's stockholmed into 'enjoying' it? Even if the MC runs away and the ML has to grovel or whatever, it could never justify what the ML did to the MC.
Manhwas that influenced this question- JINX, Roses and Champagne, Codename Anastasia, waterside night.
