Serotonina translates to "serotonin," a neurotransmitter often associated with feelings of well-being and happiness.
This word is particularly interesting because it appears at the very end of the lyrics, shifting the song's focus from personal struggles and decisions to a scientific and psychological inquiry. It hints at a deeper exploration of mental health, making it a unique and thought-provoking choice that stands out from typical song lyrics.
"Intro" opens KHEA's album Serotonina as a short spoken-word meditation rather than a sung track. He questions the idea that time heals everything, then reflects on the weight of the huge decisions he made at 17 — contracts, tours, fame — and how that pressure quietly turned his own guardian angel into something closer to a demon.
The track ends by turning outward, asking the listener to be honest about their own self-knowledge before shifting into a plain, almost clinical mention of psychiatric and depressive disorders — and the question "What is serotonin?" It's the album's framing device: naming the mental-health struggle directly before the music that follows tries to work through it.
