Arrepiento comes from the verb arrepentirse, meaning "to regret" or "to repent". It's a strong emotional word that conveys deep remorse.
In the song, the singer expresses regret about past decisions and the missed opportunity to be with someone special. He sings, "Ahora me arrepiento de lo que yo viví" (Now I regret what I lived), highlighting a pivotal moment of reflection and sorrow in the lyrics.
Nelson Arrieta and Ronald Borjas bring us a song that's all about looking back at a love that didn't quite make it. The singer remembers a specific day, seeing his love "vestida de flores con aromas de colores" [dressed in flowers with scents of colors], captivated by her smile and gaze. He admits he didn't fall in love at first sight, but her innocence and her body eventually won him over.
But as the title suggests, "Todo Quedó" [Everything Remained] in the past. He reflects on how their youthful story left an influence on his heart, and now he regrets that she's not by his side. He wishes she were there to tell him things, even though he feels happy in the present moment. It's a bittersweet feeling of remembering a love that was special, but ultimately, it "quedó entre las sombras" [remained in the shadows], a past that won't return. He even says, "toda mi vida, todo mi mundo" [all my life, all my world] was part of it, but it's all in the past now.
