Inhumano is a powerful adjective that literally means "inhuman." It's used to describe someone who is exceptionally cruel, brutal, or lacking any compassion, as if they are not even human.
In this song about heartbreak, the singer uses this word to describe his ex, singing "Me enseñaste lo inhumano... que puedes ser" (You showed me how inhuman you can be). This intense word choice reveals the depth of the pain and betrayal he experienced, making it a key part of his journey to finally forgetting her.
This song is the ultimate declaration of freedom after a bad breakup. Natanael Cano isn't just sad here; he's angry, he's defiant, and most of all, he's done. He lays it all out, accusing his ex of faking her love for him: "Te fingiste exactamente enamorada / Aunque nunca me has amado, yo lo sé" (You pretended to be exactly in love / Although you never loved me, I know it). He says she was cruel, showing him "lo inhumano y lo infeliz que puedes ser" (how inhuman and unhappy you can be).
What makes this song so satisfying is how he turns the tables. She apparently told him he'd never get over her and would come back begging. His response is the title itself, repeated like a victory cry: "Ya te olvidé" (I've already forgotten you). He fought to get over the love he had for her, and he won. Now he's flying back to a life that he says is "lejos y prohibida para ti" (far away and forbidden for you). It's a powerful way of saying, "You can't have any part of me or my life anymore."
