Not only that, but I don't think Aerith is exactly attracted to /romantically in love with Cloud either. I mean, apart from thinking he's easy on the eyes. FF7R made sure to emphasize the bits of Cloud and Aerith's interactions based of the moments of Crisis Core that IT emphasized based on ff7og moments to really drive home that Aerith is not over her first love, and is probably subconciously trying to recapture that in SOLDIER 1st Class Cloud. But I also think it goes to show she realizes after a bit that she IS doing this and that she doesn't love Cloud for Cloud, at least not yet. Maybe that'll change.
Agreed, and I personally think she never did in the OG either. I think that she could have, but I just think the tragedy of her mistaking her yearning for the ghost of Zack as being in love again is better storytelling than "I first liked him because of Zack, but then I got over that and coincidentally liked him for him, even though I never really met him".
Now don't get me wrong, I think Aerith would like Real Cloud, and I think that if Zack had never been a thing I think Aerith COULD have been attracted to Real Cloud. But Zack is a thing, and Aerith didn't meet the real Cloud and I enjoy the sad melancholy of the idea that even had she been with Cloud, he could never quite fill that hole, not because Cloud is lesser, but just because he's so alike, that a part of her would always think "it's not quite right". I think Aerith could love again, but loving someone whose this close to your lost love just draws attention to the one who is gone, it invites unwanted feelings of competition almost.
I've noticed this in real life with my aunt, she was married to my uncle (surprise), a man named "Jan", and Jan had a very distinct haircut and mustache. But he died young and suddenly and she was understandably heart broken.
A few years after that she starting dating a new man, whose name was Jan, and who had the exact same mustache and haircut, and it was just weird.
Now I am sure that by this time, 20 years later, she loves him more than she did Jan the first, but I can't not make the comparison, I can't shed the idea that while she loves Jan the second, that in part he's a stand in who is there because Jan the first is not.
I am not a fan of that concept, it feels like people making the most of a lie, it's still genuine eventually, it still works, but it just doesn't sit right with me. Because of that, even if real Cloud and Aerith were to fall head over heels in love, I could just never get behind it, I'd always think "this is wrong, and if Zack had lived Aerith would have been with him and Tifa with Cloud, which is why I could never ship it.
