Circling back to my own unpopular Seph opinions. This will be critical of some aspects of FF7 and other games featuring Sephiroth and Cloud, so if you love their dynamics in any aspect, this is your warning to keep scrolling, or read with an open mind.
I think the games (plus outside sources like Dissidia) almost constantly turning Sephiroth into little more than "obsessed with Cloud" kinda flattens his character and does him a disservice.
To me, Sephiroth only caring about interacting with Cloud doesn't add much beyond what we already know in canon. To continually focus on only that just seems like the lazy way out because well...it takes little effort to tease and bait at this point. We know the audience is there. SE knows the audience is there.
Consider that it would take more character work to let Sephiroth play off other characters - to be even a little affected by them. It would bring in something new to the tapestry to who and what he is, thus inspiring more fan lore and new engagement too. In my opinion.
Consider how Ever Crisis had a chance to add a little to the Elfe/Sephiroth interaction. It did not have to be something huge. But a moment of him being questioned, challenged, a moment of two different yet similar characters playing off each other, a moment for Sephiroth to show some introspection, and a moment to add more dynamics to Elfe, to pique fan interest.
Yet we got nothing (so far I guess but I don't hope for more). Like SE is afraid to show Sephiroth being affected by anyone/anything outside of Cloud, currently. It is as if they've reached too far into making them an inseperable villain/hero duo, and they've written themselves into a box.
I'm 50/50 on Seph-Cloud in the sense that I like the narrative parallels and symbolism. I like Cloud's character resolution. When it veers into toxic yaoi tropes, you've lost me.
It does not help that I first got really attached to Miniroth himself, and there is just something about reducing that boy to one-sided obsession that makes me...sad, for lack of better term? Plus I like Cloud enough, but outside of Tifa do not care about shipping him that much. The same cannot be said for other characters, even Tifa herself.
