Aerith is still the best girl dude.I'll let you guess which team I'm on.
The thing to put into consideration is the possibility that Aerith likes Cloud mainly due to the resemblance with Zack, who she undoubtedly still has feelings for, meanwhile Tifa is the only person who knows the real Cloud and she’s the one to fix his broken mind, if Zack somehow comes back into the picture and Aerith somehow survives (the Remake) then I reckon Aerith and Zack would start to properly like each other again, I mean hell, the fact that Aerith was on his mind until his last breathe shows the connection they had, I just don’t feel like Cloud has a better connection with Aerith personally, I think the fans do so they want Cloud and Aerith to be a thing but I don’t think Cloud as a character does personally.I don't know but I just see more chemistry with Cloud and Aerith, they barely met but his connection to her is so strong that even after her death he still lingers for her presence. Tifa, he knows her for a long time but he is friendzoning her for that long time for a reason. He doesn't feel the same connection.
