I haven't seen the epi yet, but I think shows can get away with girls liking girls more so because of how media/society actively ignores their existence more so than the fake lesbian crap made for straight men tbh. Even when girls are canonically together in media they are ignored and often just considered to be "good friends" or "gal pals" or something like that. I think because of that, SU can get away with more because they could always say "oh friendly blushing" and people would believe it.
as we all know, cis boys cannot blush. biological impossibility. the blush organ is located within the ovary
oh, sorry, i was venting about the silly disparity there, where we’ll write off women blushing at each other but can’t do the same for men
