Arrepientes comes from the verb arrepentirse, meaning "to regret" or "to repent". It's a deeply emotional word that captures a sense of remorse or a change of heart.
In the context of the song, the singer, despite being advised to forget his love, holds onto the hope that she might one day "arrepientes de todo" (regret everything). This word is central to the song's theme of enduring hope and the pain of a past relationship, making it very impactful and memorable.
"Para Qué Olvidar" is about refusing to move on. Friends keep telling the singer to forget the person he loved, and he knows they mean well, but he'd rather keep the memory than let it go.
He admits it hurts the people around him to watch him hold on, yet he doesn't feel as unhappy as they think. In his dreams she never left, and remembering her is what makes him happy now.
By the end he's still asking the same question the title poses, "why forget?", while quietly hoping she comes back one day.
