Phil Freeman from Allmusic highlighted the song as the most "surprising" and "high" of Gran City Pop, writing that "over a thunderous boom-bap beat, Rubio half-raps, half-sings about how flowers and toys won't earn her love; it's exactly the kind of culture-blending, boundary-dissolving sound that encapsulates modern Latin pop, and it's brilliant."
