The pop sound of "Deserve" from the Philippines features a steady, mid-tempo beat and a spare, clean arrangement. The song's structure alternates between a verse and a pre-chorus that builds to a more energetic, layered chorus. The melody, carried by a clean electric guitar and a synth pad, moves in a stepwise motion, creating a sense of anticipation and release. The vocals are delivered in a clear, unaffected style, with harmonies added in the chorus for emphasis. The lyrics, which are in English, express a longing for recognition and appreciation. The overall effect is one of understated emotion and quiet intensity.
