Cuestionar means "to question" or "to challenge." While it might seem like a common word, its usage in this song is particularly interesting and thought-provoking.
The lyrics state, "Nos decían en la vida no hay que cuestionar / Lo cuestionable nos llamaba para continuar" (They told us in life not to question / The questionable called us to continue). This highlights a theme of defying societal norms and expectations, suggesting that true love or connection often involves challenging what is considered conventional. It's a powerful message about independent thought and following one's own path in love.
Esteman opens on a memory: two people spending sleepless nights together while the walls seem to watch them, unsure at first why it worked so easily — "No era fácil, no era fácil sin saber por qué" ("It wasn't easy, it wasn't easy without knowing why"). The verses build into a quiet argument against convention: he and his partner were taught not to question how life is supposed to work, but chose to become "lo cuestionable" ("the questionable ones") anyway.
The chorus turns that doubt into a vow: "Si algo es eterno, lo nuestro es eterno" ("If anything is eternal, what we have is eternal"), repeated until it reads less like a hope than a fact. By the final chorus the song strips the idea down to its simplest form — rules and conditions are just fears, and loving someone properly needs nothing more complicated than love itself.
