Night and day you are the one,
Only you beneath the moon and under the sun.

These lines express an all-consuming romantic fixation: the beloved is constant across time (“night and day”) and universal across space (“beneath the moon and under the sun”). The paired celestial images intensify the sense of totality—moon and sun stand for the full cycle of experience—suggesting devotion that is uninterrupted and inescapable. The simplicity and repetition create a lyrical insistence typical of popular songcraft, where emotional certainty is conveyed through elemental contrasts rather than narrative detail. The speaker’s world is reduced to a single figure, implying both rapture and a hint of obsession.
