Don't force yourself to like something you don't. Personally I can like characters by ignoring there personalities but sometimes their personalities are impossible to ignore and I drop it. It's a natural thing not a switch to consciously turn on and off (at least for me). There are a bunch of other nice characters that are extremely hot anyways.
Many characters are drawn good-looking so just have to draw yourself back to the real world a bit for characters like these. I try to think about the person's characteristics on a real person and I get disgusted so much that I am able to drop that work and not try to tough it out to see the story through to the end.
How do you turn off your moral compass and enjoy manga just for abs and looks?(this is manga related right? hope my account won't get restricted) For example, I've seen many who got to enjoy a certain character as ml despite him being an asshole just because he is nicely drawn. I'm not being sarcastic, i genuinely want to know. I'm actually jealous of people who think like "It's just a webtoon, who cares" and keep on reading it and accepting the character. I'm not capable of that, i just can no longer enjoy the webtoon and drop it.
