After their number, host Robi Domingo first confronted Estrada with the question, "Totoo ba, are you in love with your best friend?", based on the lyrics of the song.

In response, Estrada said, "Malalaman namin ‘yan sa takdang panahon.”

Pressed by Domingo, "Pwede ba?", Ilacad replied, "Why not?", an answer Estrada echoed.
