domingo, together with his fellow housemate josef elizalde, entered the "pinoy big brother" house as the "plus housemates". their entry was given the "school rivalry" angle because they both came from schools that are considered as rivals in the philippines. during the first week, they were given the secret task of convincing their housemates that they were "best buds forever" who have been estranged for a number of years only to see each other again in the show's auditions. they were not able to succeed in their task because their ruse was discovered. domingo would go on to be part of the teen big four, eventually winning the second teen big placer award at the end of the season.
