Remordimiento means "remorse" or "regret". It describes a deep, painful feeling of guilt over something you've done wrong.
In the song, Natti Natasha sings the powerful line, "Y hoy me come el remordimiento" (And today, remorse is eating me up). This dramatic expression paints a vivid picture of being consumed by guilt, making it a memorable and advanced way to express this intense emotion.
Quien Sabe invites us into a late–night confession booth where Natti Natasha bares her soul over the sensual sway of bachata. With her trademark Dominican warmth, she speaks to a lover who is watching her crumble. She admits the hardest truth of all: the spark between them is fading because her heart never stopped belonging to someone else. The music may be seductive, yet every guitar lick echoes the sting of guilt she feels for crossing a line.
Over each chorus, Natti is haunted by the question “¿Quién sabe?”—“Who knows?”—because uncertainty now rules her world. While she clings to one embrace, she imagines her true partner being comforted in another. Pride, lies, and regret tangle together, leaving her frightened that she may lose everything. The song is a bittersweet dance between desire and conscience, reminding us that choices made in secret often echo the loudest in our hearts.
