or, How I Learned to Stop Worrying and Realize This Assgrab is Delicious
The main problem with the game's treatment of Tifa is that it gives no reason for her to actually like Cloud beyond her roping him into promising to adhere to some archaic gender trope she had internalised. Then she becomes this woman-as-saviour figure who manages to literally pull him out of psychic turmoil.
So yeah, work on that Remake team.
It's been a long time since I played FFVII, but I always got the impression that all the relationships are barely there on screen, and are mostly read into by the imagination of the players.
I agree that Tifa has no good reason to like Cloud... but by the same token, I'm not entirely sure why Cloud likes Tifa. Or Cloud likes Aerith. Or Aerith likes Cloud. The narrative seems abstracted enough that they never directly address reasons for attraction. It just kind of made sense back then that these little gendered polygons would "fall in love" after interacting with one another for so long. But it never actually fleshed out their reasons for attraction as a modern game would necessarily need to. You actually have people debating whether or not Tifa and Cloud were an item, were sleeping together, or it was just a will they-won't they situation. No game narrative later than this would be so interpretative.
It could have just been the English translation... but I thought the detail of characterization was actually a step back from the more definitive characters of VI, or the deliberate crafting of romance in VIII.
It's not necessarily a bad thing... I think the way that we were allowed to project our own reading onto these tiny polygon puppets was something special. But Square Enix has a LOT of adaptation to do to flesh out these characters into a modern narrative.
