Does anyone know FFC-Acrush? I found about them today but I'm confused because I've heard different things about them from different sources. One article said they are "androgynous girls" but then a person's comment said "they are nonbinary. they self-identify as genderless". Another person said that they use the hashtag "chinesegirls" on their Insta photos. But when I checked it out, it was a fan account for the group using the tag. I just want to know because I am seeing a lot of online debate going on about this in English right now and I want to be respectful of the group, but I haven't found anything "official" on what their gender is and I don't want to make any mistakes.
