Random relationship dynamics between two characters
No single system explains why two people click, or why they clash. It usually comes down to two forces: how they think, and how they bond. A character's personality type predicts their communication style and cognitive habits. If you pair a big-picture theorist with a detail-obsessed realist, they will naturally talk past each other. But personality only tells you what they will argue about. Their attachment style tells you how they will handle the emotional fallout: whether they pursue reassurance, withdraw into isolation, or repair the damage. By layering cognitive styles over bonding patterns, you get a realistic map of their relationship, from the predictable misunderstandings to the moments where they actually feel safe together.
