They inflict cruelty with such graceful charm that anyone would think they are being faithful.

Here, the poet captures the intoxicating paradox of love, where the beloved's cruelty is masked by such effortless charm and grace that it feels like tenderness. Their indifferent mistreatment is carried out so sweetly that any onlooker—and perhaps the lover's own yearning heart—readily mistakes it for true devotion. It paints the lover's willing surrender, finding more beauty in the beloved's graceful torment than in anyone else's genuine affection.
