Celoso means "jealous." While jealousy can sometimes be seen as a negative trait, in this song, it's presented in a more endearing and relatable way.
The singer admits, "tal vez soy un poco celoso" (maybe I'm a little jealous), acknowledging a common human emotion within the context of a loving relationship. This word is interesting because it's a strong emotion that many can relate to, making the song's narrative more personal and engaging.
Marama and Rombai's "Te Conozco" is a sweet, upbeat declaration of love and familiarity. The singer is absolutely smitten, describing his partner as "siempre tan sensual vestido de colores" [always so sensual dressed in colors] with "ojitos verdes matadores que conozco" [killer green eyes that I know]. He's been happy to have her for a while now, feeling accompanied and lucky to be with her.
He knows her so well, even from a distance, recognizing her "fragancia" [fragrance] and the "bonito en el pelo" [pretty things in her hair]. He even admits to being "un poco celoso" [a little jealous] but it's clear he's completely devoted. She's his "cocinera" [cook] sometimes, and he says he learned to be a man with her. Every time she looks at him, he feels like he's dying – in the best way possible! It's a fun, affectionate look at being deeply in love and knowing someone inside and out.
