Like it did in Drakengard. The protagonists fall for one another somewhere along the way without really noticing it at first or having a "pivotal moment", unlike in most other games, where they have a dramatic confession of some kind and the music swells and camera pans to the skies as they embrace. Things don't work like that. What should happen is that they realize over the course of their continued association that they care for one another, neither the player nor the characters involved being able to pinpoint when exactly it happened, and if the developer insists on having such a moment, it should be a quiet, almost solemn acknowledgment, that these two had found one another and held on onto each other after all that had transpired.
