So, out of the sadist girl and the masochist, the M girl is for sure more palpable. Not just because of her looks, and I for sure ain't into S&M, but just by the simple fact she doesn't force the mc into doing something. At best, she seduces him and at worst she catches him off guard and being a virgin+ her looks? Makes it very easy for him to get caught into her pace. As for the sadist, she sucks all around and is just cringey. Blackmail, coercion, manipulation, etc, generally just not a likable character IMO. But at least I can stomach it, even though seeing the mc do dress up in a bunny suit was disturbing.
As for the worst girl, the BL creeper, she can fuck off to the sun and evaporate. Girls like her are just plain disgusting. I could care less you like BL, but the second you start forcing your perversions on another person and even draw hentai based off of him with another person (especially if that is another person and not just a genuine fictional character), it's not just taking it too far, it's plain pathetic.
Either way, I understand it's for the comedy, but man, I really wish he would just say stop and not go along with it; instead of just complain about it.
