Marchitadas means "withered" or "faded." It's a poignant and evocative word that paints a vivid picture of decay and loss.
In the song, Karol G sings about looking at "las últimas rosas que me diste, aunque están marchitadas" (the last roses you gave me, even though they are withered). This word beautifully captures the lingering pain and the fading memory of a past relationship, making it a powerful and memorable choice.
In "Después De Ti", Colombian superstar KAROL G teams up with Greg Gonzalez to drop all defenses about the ugly, daily aftermath of a breakup. Forget moving on quickly; here, everyday life simply falls apart. Breakfast has no flavor, studying is impossible, and sleep is completely gone. She rejects the usual friendly advice because it feels useless from the outside: "Es tan fácil hablar cuando no te pasa a ti" ("It's so easy to talk when it's not happening to you"). Instead of going out when friends call, she lies and stays home staring at dried-up flowers ("Mirando las últimas rosas que me diste / Aunque están marchitadas" [Looking at the last roses you gave me / Even though they're withered]).
Notice the Spanish idiom "voy a cien" in the line "Ahora voy a cien por la misma avenida" ("Now I'm going at a hundred down the same avenue"). It literally means driving at 100 km/h, but idiomatically it describes speeding recklessly with a spinning head and dangerous thoughts. The lyrics balance this reckless spiral with desperate wishful thinking, admitting to inventing daydreams ("fabrico fantasías") where the ex is still around to take care of her, hoping someone will step in and prove that the whole breakup is just a lie.
