Una Flor invites us into a dreamlike confession where Ozuna wrestles with guilt, loss, and the haunting persistence of memory. The song opens with mysterious knocks at the door and a voice that keeps speaking even while you sleep, painting the picture of a love that lingers like a phantom. Ozuna admits his own flaws—he has lied, sinned, and surrendered to passion—yet he still shines "ser de luz" in moments of tenderness. The repeated image of a flower dying in a color he will never see again symbolizes a once-in-a-lifetime love that has withered beyond revival.
Wrapped in a smooth trap rhythm, the lyrics move between sorrow and hope. Even as he watches love "morir," Ozuna clings to the fragrance of his lover’s clothes, a photograph under his pillow, and a heartfelt plea to God to keep protecting her. The song becomes a blend of confession, nostalgia, and spiritual longing, reminding listeners that some loves leave a mark so vivid that not even time, distance, or death can erase it.
