Rendirme means "to give up" or "to surrender." It's a strong verb that conveys a sense of resignation or defeat, often after a struggle.
In "Inevitable," the singer expresses a conflict: "Yo no quiero rendirme, pero no tengo más que darte" (I don't want to give up, but I have nothing left to give you). This highlights the emotional struggle of wanting to fight for a relationship but realizing it's futile, making it a poignant and relatable word in the context of a failing love.
Dvicio frontman Andrés Ceballos is singing to someone he already knows is gone, even though nobody has said it. It opens on a night she never called — "Ya son las 9 de la noche y tu sigues sin llamar" ("It's already 9pm and you still haven't called") — before he lists what actually killed it: "Conozco bien tu doble cara y tu papel de niña buena" ("I know your double face well, and your good-girl act").
He's not pretending he wants this. The chorus keeps saying "Yo no quiero acabar contigo, pero el destino escribió que ni siquiera como amigos podamos seguir tu y yo" ("I don't want this to end with you, but fate wrote that we can't even stay friends"). "El fuego está quemándonos" ("The fire is burning us") — every step from here is a mistake, and that's the title: nothing either of them chose, just where the two of them ran out of road.
