To do this, Maria had to give up one of her biggest dreams, which was to be a singer, and instead went to work in a building in Brasília. One day, Elza was selected to compose a musical and in this offer, Maria found the perfect chance to revive her dream in her daughter, doing everything to make the girl experience this show.
