In La Camisa Negra by Juanes, the singer expresses his pain and sorrow after being abandoned by his lover. He wears a black shirt to symbolize his grief and loneliness, and reflects on how he was deceived by his partner's false promises. He laments his misfortune in having met her, and how he was left broken-hearted and full of sorrow after tasting the bitter poison of her love. He is left with only his black shirt and a dead heart beneath it.
