I don't think Kylo and Rey will be in "a relationship", per se. But I can easily see what most people and reviewers are seeing. They have electricity between them, and that sells in Hollywood. I disagree about Daisy Ridley and John Boyega. They don't have romantic chemistry AT ALL. The flavor between them is very friendshippy. Very easygoing. And JJ and LF saw it and called it. That "romance" ship has totally sailed.
