El lado oscuro

The speaker contrasts their own difficult or “dark” background with the other person’s apparently more fortunate start. Despite this difference, they speak openly about love and say they are no longer afraid of being left or leaving. The repeated declarations suggest strong affection, but also a sense that the relationship may have changed: the loved person is described as someone who “had been” the most beautiful.

The “good side” and “dark side” of the world are images for unequal experiences of life, not necessarily literal places. A “mark” of the dark side suggests a lasting sense of hardship or shame, though the speaker says they do not blush when expressing love. Comparing the beloved to the brightest star makes them seem extraordinary. Asking how to “earn heaven” may express the speaker’s worry about deserving happiness or reward through love.

The lyrics can be heard as both a confident love declaration and a bittersweet reflection. The speaker’s fearlessness may show emotional courage, or it may mean they have accepted that separation is possible. The past-tense description of the beloved leaves open whether the relationship is ending, already over, or simply being remembered. The song does not explain what made the speaker’s life “dark,” so that contrast remains personal and open to interpretation.
