The song captures the emotional turbulence of being deeply in love, specifically the feeling of being "nababalisa" (anxious or restless) when in the presence of a loved one. Key lyrical themes include:

: Lumenda's cover was performed with explicit permission from the copyright owner and has even seen live collaborations between the two artists.

: Day and night, the subject of their affection is the "dahilan" (reason) for everything—from sleeplessness to a pounding heart.

: Lumenda’s version often features a softer, more melodic arrangement—sometimes just a keyboard and vocals—which emphasizes the vulnerability of the lyrics.
