"Se Acabo La Química" is a song by Espinoza Paz, a Mexican singer-songwriter. The song talks about the end of a toxic and dysfunctional relationship. In the lyrics, Espinoza Paz expresses that he has moved on from the person he is singing about. He compares himself to soap that slips away from a million times the person slept in someone else's arms. He had surpassed his feelings for this person and is no longer affected by them. He feels sorry for the person because their world is now upside down. Although they may have had something in the past, it no longer matters. The numbers don't lie, and they had deceived him multiple times. The chemistry between them has ended because the person is not peaceful or tranquil. Espinoza Paz couldn't stay with them just because of their physical beauty. The relationship was toxic, and the person was unable to give their all in practice. The person comes back, expressing regret, but Espinoza Paz knows that they never valued him before. They can beg for forgiveness, but it doesn't change the fact that the relationship is over. No one sees them together anymore, which explains everything. The person was egocentric and self-centered. Overall, "Se Acabo La Química" tells the story of a relationship that had its ups and downs but ultimately ended due to toxicity and the lack of genuine care from one person.
