@KrimzonHawka What social pressure? It's common sense and decency to not openly objectify other people based on their appearance. Just like you have freedom of fetishes, other people have their own freedom to stay out of it. Besides, I wouldn't be too happy to find out that a person I like talks to me just because of the shape of my pinky toe or something.
And while it's a good thing to be supportive of your friends, you also have a responsibility to watch out for them. The friend in question was sympathetic to the female lead, her main concern was how others would not be so kind. Which is not hard to image, considering this story is set in South Korea.
Unless I missed the part where the friend advised the female lead to scream like she's being assaulted, I don't see how it's her responsibility.
