• In "X Si Volvemos," Karol G and Romeo Santos tackle the subject of a broken relationship. They acknowledge the difficulties in separating due to lingering physical attraction and the complications it brings.
• The romance the two shared was toxic. Indeed, Karol refers to Santos as a gangster, and herself as a bandit.
  
  Yo soy bandida y tú eres gánster
  
  She also admits their union was a disaster.
  
  Ya sé que en el amor somo' un desastre
  
  But they have great chemistry in bed. In the chorus, Karol and Santos agree to one more intimate night together before they say goodbye.
  
  Vamo' a hacerlo por última vez, bebé
  Que en el amor no, pero en la cama nos entendemos
  
  (Translates as "Let's do it for the last time, baby
  Not in love, but in bed we understand each other")
• The song's title translates into English as "In Case We Come Back." Though it doesn't appear in the lyrics, it sums up the song's thesis of a couple that is incompatible outside the bedroom. Such is their sexual chemistry, both agree to leave the door open for future lovemaking rendezvous.
• Karol originally recorded "X Si Volvemos" solo and shared a sneak peek on TikTok. Then she had the idea of Santos joining her on the song, so she reached out to the American singer. Santos responded by informing her he had already come across the song on TikTok and had created a video with its audio for his social media.
• Karol G's regular collaborator, Dominican Republic producer Ovy on the Drums, helmed the sultry reggaeton bop.
