Laberinto literally means "labyrinth" or "maze". It's a visually powerful word that you don't often hear in pop songs.
In "Amar De Nuevo," Rauw Alejandro uses it as a metaphor for his own complex emotions after being hurt. By singing "Soy un laberinto sin salida" (I'm a labyrinth with no exit), he's warning his new love that he's difficult to understand and lost within his own feelings, making him a challenge to love.
In "Amar De Nuevo," Puerto Rican star Rauw Alejandro struggles between the fear of getting hurt and the excitement of a new crush. Past breakups left him feeling damaged, calling himself "un laberinto sin salida" ("a maze with no exit"). He bluntly admits, "Baby, no confío en esto del amor" ("Baby, I don't trust this love thing"), because his previous relationships went from bad to worse. But being around this new person changes his mood instantly: "mi pasado no existe" ("my past doesn't exist") and "se me había olvidado lo fácil que es reír" ("I had forgotten how easy it is to laugh").
Throughout the track, he asks his partner to take the lead and be patient: "Enséñame a amar de nuevo" ("Teach me to love again"). You also get plenty of Puerto Rican slang that makes his late-night thoughts feel personal. When he stays awake overthinking, he calls it his "maquineo" (a slang term for plotting or overthinking in your head). Later, he uses "bellaquita" (feeling horny or sexually turned on) to describe how quickly their chemistry can ignite after a long night. By the end, he leaves an ex in the dust, glad that an angel showed up to heal his old wounds.
