[8] According to TN, on the song, Tini "opens her heart and shows her most vulnerable side, referring to the complex stages of depression she went through" with connections to her breakup with Argentine footballer Rodrigo De Paul.

[10] "Today Buenos Aires hurts," says Tini in the song, after she "always referred to how much she loves the city and how good it made her to be in it", after months of touring with Argentine telenovela Violetta or in her solo career.

[11] El Canal de la Musica for Crónica TV claimed that on the song, Tini "continues to demonstrate her versatility and talent as an artist, conquering hearts [...] and leaving an indelible mark in the music industry".
