Envolviéndonos comes from the verb envolver, meaning "to wrap" or "to envelop." The -nos ending makes it reflexive, so it means "enveloping ourselves."
In the song, Paula Arenas sings, "Envolviéndonos en ellas" (enveloping ourselves in them), referring to the stars. It's a beautiful and evocative word that paints a picture of being completely immersed and surrounded by a magical experience, highlighting the romantic and dreamlike atmosphere of the lyrics.
Paula Arenas built 'Es Natural' around a simple dare: stop overthinking and let attraction run its course. The verses move through skin and breath rather than declarations — 'Boca a boca sin hablar' [Mouth to mouth, without speaking] and 'Caminando en tu piel' [Walking on your skin] — building toward a chorus that treats desire as instinct rather than choice: 'Como los dos, solo los dos, el instinto es natural' [Like the two of us, just the two of us, instinct is natural].
By the second verse she's ready to trade reason for the moment entirely — 'Olvidemos la razón y juntos descubramos las estrellas' [Let's forget reason and together discover the stars] — landing on the same idea each time the chorus returns: whatever's happening between them doesn't need explaining, it just needs following.
