Well yes and and no. Yes, women and be broody and aloof, but there are certain ways that guys act that girls just don't and vis versa. There's a kind of behavior culture between the genders, right down to the way people speak. Like when you lower the pitch of a woman speaking, it sounds like a guy doing a bad drag voice, not a regular guy. Same with guys doing a falsetto. Even the butchest lesbian still has some feminine tendencies, otherwise, other lesbians probably wouldn't date them. Gay people aren't just pallet swaps of straight people.
The way Claude speaks, how he handles rivals/opposition, his choices, all fit men better than they do masculine women. I realize it is common now to see women act like men in fiction, but the fact is masculine women act differently than men, just like feminine men act differently than women. Similar, but not the same. If you're asking for a gender swap just for the aesthetics, I have to ask, is that fetishizing gay people?
Tbh I have to disagree with that. I think you have something backwards. Gender is just an attribute to who you are, not the other way around. Personality, mannerisms, etc are all unique to each individual and I honestly find it strange that there is a need to categorize what counts as "feminine" or "masculine" or divide actions into what a guy would do or girl would do. Youre asking why people see this as yuri and it's because we see the artist depicting 2 girls - that's literally all there is to it.
I've seen a lot of comments about how this feels like a yuri, but to me Claude/Chloe acts like a guy in every scene. Everything about his personality just screams broody/aloof guy to me. Even the way he's drawn feels like a teenage boy with a wig and a dress, or a bad aesthetic swap (especially when he's wearing the big hat.) I'm clearly missing something here. So can someone explain to me how this feels like yuri, aside from the ml gender bending? Because I was kinda given the impression by my gay friends that if you can swap a gay couple for a straight couple and have the dynamic be the same, you're doing it wrong.
