Does anyone here think it could be both girls in the romantic sense?
I used to. Until Remake's second half and now Rebirth.
I saw a shift in how they were developing him and Aerith's story and it's basically with Her not being sure she likes Him in that sense. And him completely oblivious to her feelings in the first place. Then him finding out about Zack being Aerith's boyfriend who in his eyes she still is head over heels for he needs to tell her what happened to him. This way the devs don't have to say anything about Cloud's feelings. He remains oblivious because he now has no reason to entertain Aerith having feelings for him.
I definitely think before Remake though you can make the case. Like in OG? We can argue both girls were people he was interested in. I don't believe in OG there was no romantic implications there. But because Aerith dies they never needed to be explored. Cloud is also canonically oblivious to her feelings there too. Their feelings toward eachother could just remain ambiguous and it didn't affect the story. I definitely saw it as non platonic and still don't think it's anything but non platonic. But things are now more defined.
And over time the developers had to chose a lane and made things less ambiguous especially with Crisis Core and Advent Children Complete pushed Zerith because they didn't want the audience to think Cloud was some jerk using Tifa and leaving her in AC.
Remake then has Aerith knowing the future of CT and cheering them on. She is very obviously not interested in pursuing Cloud as she was in OG. Then Rebirth has her lose those future memories and get conflicted with her feelings and kind of pursuing Cloud while he thinks the entire time she has feelings for Zack and he learns of Tifa's feelings early on and reciprocates.
While Aerith confesses she isn't sure what she feels. To me that's the devs completely closing any window of Cloud entertaining the thought of Aerith into him or him thinking he should be interested in her. Now why would they need to make their protagonist think about a romance he is A. Oblivious to. B. Not entertaining because he thinks she loves someone else. C. Not thinking about because He loves someone else D. SHE isn't even sure about now. What would be the point of putting romance between them in this scenario?
Since these are not the cases in OG I treat them separately and entertain the idea their could have been something there but with all this new context the Lifestream scene with Tifa especially this time around brings his feelings for Tifa up in a way that something with Aerith becomes pointless to explore. Especially with the final nail being Aerith herself unsure if he even likes him romantically. There is now zero reason to have these characters explore feelings for eachother from both their perspectives. It now does not matter if Cloud feels romantically toward her or not if Aerith herself now has no reason to entertain thoughts of future romance with Cloud. They basically made it so now neither character has reason to pursue the other from this point onward.
Then they are building up Zack and his feelings for Aerith and they're making Cloud basically have romance moments earlier on with Tifa showing him reciprocating etc and well almost kissing her in Gongaga even seperate from kissing her on the date.
So now that entire ambiguous idea of CA romance even if brought up as fanservice hints can now be completely ignored by the story in the end. To make him fall in love with in Aerith After all that?? I don't think they would. And now I'm convinced they won't.
Especially now that they have set all their story up to reunite with another person that isn't eachother. Could Pt3 prove me wrong? We will see. But I don't think so.

And edit: And I'm a Clerith and I wish that the above was not my thoughts on this matter. If anyone thinks this is the way I had imagined or wanted things to go with Even Aerith being unsure of her feelings?? It's definitely not the case. I didn't ask for that. And I don't like it, no. I would have preferred OG scenario to remain untouched or even unrequited love with her accepting her own feelings honestly but knowing what she felt.
But I write this because that's honestly what I see them doing. And basically I see it as IF the endgame payoff is mutual romance for eachother it's pretty much the worst idea to put Aerith asking herself Edit the extent of her feelings right before her farewell as "knowing where they stand" and while having another guy she said she might still have feelings wait for her return even in another world. To me that's the way they got out of having to explore the issue of romance further honestly.
