Her first regular show was "Mangarap Ka" (2004), an afternoon television drama directed by Cathy Garcia-Molina and Malu Sevilla. It starred Piolo Pascual as Oslec and Angelica Panganiban as Cutie.
Then 7-year-old Miles played the role of one of the streetchildren on the streets of Quiapo. Her audition story for the said show was a funny one. As all callbacks go, she went to the set garbed in nice clothes, blow-dryed hair, and even wearing a nice set of false teeth--only to find out that the directors were looking for actors fit to portray the kids of downtown Manila.
Direk Cathy asked if she can cut her waist-length hair to make her look like a boy as part of the narrative. "So ako, okay lang sa akin kasi feel na feel ko naman. Gusto ko naman mag-artista." Miles was to play the role of young boy Pepe. Like the viewing public, a number of people on the set actually thought that she is a boy. "Yung ibang audio man, pag kakabitan ako ng lapel, nagtataka sila bakit daw 'yung underwear ko pambabae, e lalaki daw ako," Miles quipped. "Lahat ng babae sa Quiapo, crush nila ako. Kasi akala nila lalaki ako." When it was later revealed in the story that she is actually the young girl Pepay, a lot of people were surprised.
Miles in Goin Bulilit
Her next project was "Goin Bulilit," a sketch comedy show by kids and for kids. "For me, 'yun 'yung for me na naging unang pamilya ko sa industry. Kasi parang di kami nagtatrabaho do'n, naglalaro lang kami." Miles recalled how she and her batchmates would play noisily in between takes, much to the dismay of the guards on the nearby studio.
She stayed in the show until she graduated with the sixth batch at the age of 12. "Pinakaunang show na talagang mahal na mahal ko kasi lahat kami pamilya. Pati mga staff, mga crew, sila direk. Pamilya talaga kami." While still doing the weekend comedy show, Miles was casted along with four Goin Bulilit co-actors for "Mga Anghel na Walang Langit" (2005-2006). Inspired by the 1970s film of the same title, it tackles the story of the lives of unfortunate and exploited children. Because of high ratings, the show stayed on air for nine months.
