Odisea is the Spanish word for "odyssey", referring to a long, eventful, and adventurous journey, like the one in the epic Greek poem.
In this song about a painful breakup, Ozuna sings "No vuelvo a pasar la misma odisea" (I won't go through the same odyssey again). He uses this powerful, literary word as a metaphor for a complicated and difficult relationship, elevating the song's emotion and making it a very unique word to find in a reggaeton track.
This song is a blunt and emotional farewell to a relationship that's gone cold. The singers feel like their partner has completely changed, saying, "Ya no me miras igual / No eres la mujer que conocí" (You don't look at me the same / You're not the woman I knew). There's no effort to fix things, and they've decided to leave for their own "paz mental" (mental peace). It's a clean break: he's deleting her from social media and tells her not to call him when she's drunk.
The lyrics get more specific and intense, accusing the ex-partner of using him and being a hypocrite. Anuel AA drops a particularly sharp line: "No aceptaba' a mis hermanos, pero sin yo saberlo / Me tenías jangueando con tu ex" (You didn't accept my friends, but without me knowing / You had me hanging out with your ex). The song is about recognizing that a relationship is broken beyond repair and making the difficult choice to walk away to protect yourself.
