Padezco is a dramatic verb meaning "to suffer from," typically used when talking about a chronic illness. It's a more poetic and intense word than the more common verb sufrir (to suffer).
In this bachata classic, Romeo Santos sings "Yo tan joven padezco del corazón" (Being so young, I suffer from a heart condition). He uses this powerful word to treat his overwhelming love like a disease he's happily afflicted with, perfectly capturing the song's passionate drama.
Get ready for a massive collaboration between the King of Bachata, Romeo Santos, and R&B superstar Usher! In "Promise," they're not just falling in love, they are completely losing their footing. Romeo opens by saying, "He perdido el balance por tu amor" [I've lost my balance for your love], and Usher agrees, "Try to keep my balance but I still fall." They're so overwhelmed that love feels like a trap, but one they don't want to escape. Romeo gets pretty dramatic about it, calling his lover's body a jail where he's a happy prisoner: "Tu cuerpo es la cárcel y yo un prisionero / Y jamás quiero salir" [Your body is the jail and I'm a prisoner / And I never want to leave].
Because the feeling is so intense, they're terrified of getting hurt. Both singers are basically begging for reassurance before they give their hearts away completely. They sing, "Quiero ser tuyo enterito pero tengo miedo" [I want to be all yours but I'm scared]. So, they ask for a promise to be loved "way past forever." It's a song about that scary, thrilling moment of total surrender to another person, when you feel like you can't live without them and just need to know they feel the same.
