Celos is the Spanish word for "jealousy", a powerful emotion that's central to many dramatic stories. It's a fantastic word for expressing the complicated feelings that come with love and heartbreak.
In the song, Rauw Alejandro sings "Aquellos celos tan intensos que sentí por ti" (That intense jealousy I felt for you). He uses this word to confess the raw, overwhelming passion he felt, adding a layer of drama to this story of unrequited love.
Puerto Rican reggaeton star Rauw Alejandro takes on a classic salsa breakup narrative in "Tú Con Él", and the story hits like a punch to the gut. The narrator finds out the hard truth: he was just a temporary rebound. He admits it bluntly with "Yo solamente fui la excusa para hacerle ver que tú podías... vivir sin su amor" ("I was only the excuse to make him see that you could... live without his love"). While she has gone back to her original partner, he is left counting the hours alone ("El tiempo corre, yo te espero pero tú con él" [Time flies, I wait for you but you are with him]).
Even with a bruised ego, he cannot bring himself to hate her. People keep telling him she looks prettier than ever ("estás linda mucho más que ayer" [you are pretty, much more than yesterday]) and that she still asks about him. He looks back at his own jealousy, asking for forgiveness ("Discúlpame aquellos celos tan intensos" [Forgive me for that intense jealousy]), before accepting that he got played in a game he did not realize he joined: "Todo fue un juego... Pero en ese juego yo me enamoré" ("Everything was a game... But in that game, I fell in love"). By the end, he calls her "mamita" (an affectionate Puerto Rican term for a woman) and swears that he has finally woken up from the illusion.
