The group (who lead the cast of young actors in the show) recorded their second studio album and toured while on break.

"Nuestro Amor" was released on 25 August as the album's lead single, and it was used as the new theme song for the show.

The song is assumed to be sung from the point of view of the actors' characters in the telenovela, although Alfonso and Anahí don't sing together like Dulce and Christopher.

The male members get ready for the romantic dinner, too, in a Japanese-looking house, where they look for the girls as they had left clues for them in order to find them.

Finally, the band walk outside and sit around, sing, enjoy the moonlight and oddly, share some bottles of milk from which they drink.
