Delirante translates to "delirious" or "raving." It's an intriguing word that goes beyond common vocabulary, suggesting an intense, almost irrational state of mind.
In the song, the narrator admits, "Siempre he sido delirante en mis antojos" (I have always been delirious in my cravings). This reveals a deep-seated impulsiveness and a tendency to be overwhelmed by desires, making it a powerful and memorable word to feature.
This song is a really interesting look at regret and a breakup. The singer admits he messed up, saying "Sólo la pude dañar" [I could only hurt her] and "No fui sincero" [I wasn't sincere]. He remembers she wanted to feel like she was in a fairy tale, and he was her first love, trying to teach him how to love.
But here's where it gets complicated! He wants a friend to tell her he's still around, "Aquí sigo" [Here I remain], even though he has no reason to live without her. He also says he doesn't want her back because he doesn't want to hurt her again. Then, he asks his friend to lie! He wants the friend to tell her he's strong and didn't care about losing her, and even to say he has someone else, all so she doesn't worry. It's a pretty intense mix of guilt, self-preservation, and a desire for her to be okay, even if it means deceiving her.
